Celebrating Cajal: A Legacy in Line, Light, and Thought

The 173rd birthday of Santiago Ramón y Cajal (1852–1934) will occur on May 1,  2025.

I celebrate his birthday as he continues to influence brain science through both his groundbreaking scientific work and his remarkable visual  creativity.

For over a decade, I’ve explored the intertwined relationship between art, identity, and science through the legacy of Cajal. My first encounter with his drawings—those haunting, gestural renderings of neurons—was nothing short of transformational. I wasn’t yet aware of his stature in neuroscience. I simply saw drawings that felt alive, breathing in implied space, extending thought through line. What struck me was not just their anatomical accuracy, but the deep perceptual observation embedded within them. Unlike the topographical containment of Camillo Golgi’s work, Cajal’s drawings seemed discovered, not designed—a collaboration between eye, hand, and wonder.

This journey led me across disciplines and continents, including a Fulbright España Senior Research Fellowship at the Instituto Cajal in Madrid. It also shaped my long-term visual art project Aesthetic Instincts: The Intersection of Art and Science in the Life of Santiago Ramón y Cajal—a body of work that fuses historical research, observational drawing, surreal imagery, and personal interpretation.

The drawing uses colors that differ from those of the stains in the original histologic specimens. This drawing was reproduced (SR Cajal 1895) with the following color codes: neuroglia in brown, nerve cells in blue, fibers that cross the gray substance in red, and the collaterals and fibers of the white substance in black. Ependymal cells are also colored in brown. Image courtesy of the Archivo científico Fernando de Castro.

I'm honored to have two recent publications that explore these ideas:

"Art, Intuition, and Identity in Ramón y Cajal" — published in The Neuroscientist (Vol. 31, Issue 2, April 2025), co-authored with Javier DeFelipe, Arpan R. Mehta, and Bevil R. Conway. This essay examines how Cajal’s artistic training and aesthetic choices were central to his scientific legacy. His self-fashioning through drawing and photography, his use of metaphor and allegory, and his Dürer-inspired visual strategies all reveal a man who did not separate science from selfhood. Read the article here: https://journals.sagepub.com/doi/full/10.1177/10738584241234049

"Drawn To, Drawn From Experience" — featured in the newly released book Circulating Now, Full Circle, published by Virginia Tech and the National Library of Medicine. My essay (pp. 229–235) explores my first encounter with Cajal’s drawings and the phenomenological experience of discovery—what it means to see something new not through data, but through presence. It’s part of a larger conversation about how historical archives can ignite both research and imagination. 

As Cajal once wrote, "Only artists devote themselves to science." He believed that beauty and intuition were not embellishments, but essential instruments of discovery.

His life reminds us that seeing—truly seeing—is an act of synthesis. It draws on memory, biology, curiosity, and love.

On May 1st, I will, as every year, celebrate Cajal not only as the father of modern neuroscience, but as an artist of perception, and as a kindred spirit whose drawings continue to shape the contours of my own work, both in studio and in scholarship.

The vertebrate retina is another good example of Cajal’s Law of Dynamic Polarization.  Because he knew from which direction the stimulus to the photoreceptors (at the top of the diagram) originated, it was clear that information ought to be transmitted inwards, through axons of the photoreceptors to the dendrites of the horizontal and ganglion cells, and onward into the visual cortex, as noted by the arrows on the diagram above.  In addition to the usual retinal information flow, Cajal illustrated some more unusual directions for information transmission.  He noted information flowing from c to I, along the cell body of a horizontal cell, although this subsequently has not been found to be a viable signal path.  Likewise, visual signals in many amacrine cells, shown to the right of D, need not pass through the cell body, contradicting the apparent intent of Cajal’s arrows. While Cajal may have erred in these two instances, he correctly observed another unusual signaling pathway between G and H: these axons from the visual cortex are returning to the retina and transmitting information to the amacrine cells.  This phenomenon has indeed been observed in present day, but not in all vertebrates; significant centrifugal input is a hallmark of avian eyes in particular.

Legacy and Insights: Celebrating Santiago Ramón y Cajal Through Art and Science

Part 1: Celebrating Santiago Ramón y Cajal on the 172nd Anniversary of His Birth

May 1, 2024, marks the 172nd anniversary of Santiago Ramón y Cajal's birth. To commemorate this occasion, I am sharing my latest drawings from the Cajal Inventory, created during a recent trip to Madrid. These include a portrait of Cajal and a composite caricature of visitors at the National Museum of Natural Sciences. The museum currently hosts an exhibition titled "The Historical Legacy of Santiago Ramón y Cajal," featuring his workspace with original furnishings and personal items. This exhibition also displays over 28,000 artifacts from the Cajal Legacy, maintained under the supervision of the CSIC.

Santiago Ramón y Cajal's contributions include his progression from a Licentiate in Medicine to various professorships, ultimately securing a chair in Histology and Pathological Anatomy in Madrid. His notable publications include the Textura del sistema nervioso del hombre y de los vertebrados among over 100 journal articles. Cajal received numerous awards, including the Nobel Prize in 1906, memberships in royal academies, and honorary degrees from universities such as Cambridge and Clark. His influence extends beyond his lifetime, highlighted by ongoing recognitions such as the publication by the Caroline Institute on his centenary.

Part 2: Updates on Scholarly Pursuits and Exploration of Cajal's Work

“The histologist . . . has two important adversaries the smallness and the colorless”, wrote Cajal in Recuerdos de mi vida (1917, p. 337, translated here by DeFelipe).

I am pleased to announce the publication of Art, Intuition, and Identity in Ramón y Cajal in the History of Neuroscience section of The Neuroscientist. I extend my gratitude to my coauthor, Javier DeFelipe, for his pivotal insights on Cajal and to Bevil Conway for his mentorship in scholarly writing. Arpan Mehta of the Cajal Embroidery Project also played a crucial role in the success of our collaboration, starting with our initial six-hour discussion in 2021.

Our essay examines Cajal's legacy, emphasizing his artistic skills alongside his scientific innovations. Cajal's methodical use of the Golgi method, complemented by various histological dyes, provided deep insights into brain structure and function. He adeptly combined his artistic talent with scientific research, using techniques like photography to enhance public engagement with his anatomical sketches. This blend not only solidified his professional image but also left a lasting impact on both the scientific and cultural landscapes.

Threaded Pathways: Unraveling Neuroscience and Art in Hannah Warming's Needles & Neurons

Welcome to my latest blog entry, a space where the artistry of Santiago Ramón y Cajal, the legendary Spanish Neuroscientist, becomes the muse for a unique fusion of science and art. As an artist, professor, and Fulbright Scholar, I have the privilege of exploring and breathing "the life" of Cajal's intricate scientific sketches within the four walls of my studio. Just as the swirling hues of a nebula inspire the astronomer, the delicate complexities of Cajal's drawings breathe inspiration into my work.

Cajal's life, filled with discovery and dedication to neuroscience, forms the bedrock of my artistry. His meticulously crafted drawings are not just records of the earliest ventures into the intricate labyrinth of the human brain but also beautiful works of art that capture the fascination and wonder that the human brain inspires.

In this post, we'll embark on a journey to explore Neuroscientist and emerging artist Dr. Hannah Warming. She is the founder of 'Needles & Neurons,' a burgeoning movement within the art world where neuroscience melds with the age-old art of embroidery. Needles & Neurons mission is to raise money for Alzheimer's Research by selling finished embroideries, embroidery patterns, and kits. This emerging artistic expression reflects a blurring of the lines between scientific exploration and creative expression, much like Cajal did with his illustrative documentation of Neuroscience. 

Hannah's work is far from being merely popular; it is critically acclaimed and deeply respected in both Neuroscience and artistic communities. To this recognition, her works have graced the cover of the prestigious Lancet journal and featured prominently in the Journal Consilience. But beyond creating beautiful, intellectually engaging art, Hannah's work also has a profoundly humanitarian dimension. Each sale of her embroidery designs contributes to Alzheimer's Research UK, raising significant funds to support research into this devastating disease.

Her creations push traditional needlework boundaries, weaving in drawing and painting elements to deepen the conceptual connections between form and content. She uses social media platforms to share her creative journey and underline scientific research's importance, sparking dialogues and connections with her ever-growing audience. This vibrant engagement has led to special graphic design commissions from the international community, further amplifying her impact.

Needles & Neurons is more than an artistic endeavor; it's a labor of love. Each piece that Hannah crafts are wrapped with care and shipped to collectors with personal touches like custom stickers and thoughtful thank-you notes. Despite her bustling schedule as a postdoc researcher at the University of Oxford, Hannah found time to share her passion and the important work she's doing in an interview for this blog post. She firmly believes in the power of creativity to effect change and raise awareness, with each stitch serving as a testament to this belief. You can support this critical cause and own a piece of this beautiful artistry through her Ko-Fi and Etsy stores.

Now, let's examine briefly some of the scientific methods that underpin some of Dr. Warming's inspiration for these artworks: electrophysiology. This cutting-edge technique allows researchers to capture and study the electrical symphony that orchestrates our neural activity. By gently introducing a minuscule electrode into a neuron, scientists can measure the shifts in voltage as the neuron engages, providing valuable insight into the communication patterns of these complex cells.

An electrophysiologist often finds themselves at the forefront of these intricate studies. Armed with micropipettes, they meticulously record electrical signals emanating from cells. Every bit of data gathered brings them a step closer to understanding the secrets of how these cells operate and interact, thereby opening up possibilities for new treatment methodologies for various neurological disorders.

Picture this: a dedicated neuroscientist in the laboratory, a micropipette carefully positioned to contact a neuron, adjusting and fine-tuning the parameters to capture the purest signal. Dr. Hannah Warming has experienced that as she anticipates with excitement the treasure trove of new data she is collecting, knowing that hours of analysis and discovery lie ahead.

She once noted, "When I engage in electrophysiology, my interaction with the cells goes beyond mere observation. I literally touch and manipulate them. I place the pipette against the cell membrane, delicately breach it, and start recording the inner electrical currents. It's an intimate dance of science and discovery."

Dr. Hannah Warming | Interview Questions:

Dawn: What inspired you to begin embroidery work? How did it all get started?

Hannah: Like many other creatives, I picked up new hobbies to keep myself busy during the Covid-19 pandemic lockdowns – as the first lockdown loomed in early 2020, I tried out a floral embroidery kit to teach myself a few stitches and was hooked right away. Once I had completed the kit, I looked for ideas of what to stitch next, and as I was stuck at home and missing the lab, I tried out embroidering a neuron with a patch clamp pipette – my first piece of science art! It was a bit wonky, but I loved how easily embroidery came to me and how therapeutic it was as an art form.

Dawn: Have you always created artwork?

Hannah: Since childhood, I have loved to draw and paint, but I never felt I was particularly "good" at getting the image in my head onto the paper - so for many years, I fell out of touch with my creative side. I had tried crochet in the past (inspired by my very talented sister!), however, I couldn't seem to get the tension right, and everything looked a bit wonky. With embroidery, something just clicked, and it felt like finally, I was able to get my ideas out in an accurate way. I love how the threads closely resemble the axons and neurites I see in my cells in the lab and the different textures you can create with one medium. 

Dawn: What inspired you to raise money for Alzheimer's research?

Hannah: During my Master's degree research and Ph.D. studies, I was part of a lab that primarily focused on Alzheimer's disease, although my own research was in other neuroscience topics. Our lab was supported significantly by funding from the charity Alzheimer's Research UK, who facilitated many great opportunities for me and my colleagues, such as conference attendances and networking meetings to aid our development as scientists and drive research forwards. I decided I wanted to use the new hobby & my accumulating stack of finished embroideries to raise funds and give something back, so ARUK was the clear choice! 

ARUK works hard to support research into improving not only the future for people with dementia with new diagnostics and treatments, but also to improve quality of life for those currently affected by the disease. Recently, much of the industrial research funding into neuroscience and diseases like Alzheimer's has been withdrawn as these conditions are difficult to treat and therefore not "profitable" enough, and so to see change in the future, the support of organizations like ARUK is a necessity.

Dawn: How do you decide what you want to embroider? Do you design all of your work?

Hannah: I design almost all of my embroideries, usually with a brief sketch on my iPad first to decide on placement and color options. Any that aren't my own design are usually based on the drawings of Ramón y Cajal – his intricate drawings of neurons are the perfect inspiration! I also like to copy my own microscopy from my lab work, if I take a particularly nice photo of a cell I have made recordings from.

I go through phases of what will be the subject of my designs based on what I see in my research – for example, when I was growing bacterial cultures in the lab to isolate DNA, I made some beaded petri dishes mimicking bacterial colonies. Nowadays, I spend time on the microscope imaging neurons I have made recordings from, and these are inspiring my current works. 

I have also had the pleasure of making many commissioned embroideries, usually as gifts for my customers' colleagues or graduating students. I believe the art should be scientifically accurate – this is a fun way to learn about new topics and cell types so that I can generate a design and stitch something that the recipient can enjoy as being personal to them. I love having such a wide array of subjects for my embroidery designs!

Dawn: Your Master's is in Biomedical Science; what led you to neuroscience research?

Hannah: I remember saying during my undergraduate study that "I will never work in neuroscience," as I just did not enjoy it at all, to begin with! Over time I developed an interest in neurodegenerative disease and chose to take more modules on the topic. My Master's thesis was in the study of NMDA receptors, a type of protein that facilitates excitation through cell membranes and a key mediator of cell-to-cell communication. Our lab discovered a new form of the receptor that hadn't been previously identified in humans, which I found so exciting, and it led me to become very interested in the mechanisms of cell communication. This is also where I first tried patch-clamp as a technique and loved it.

From there, I decided to combine my interest in neurodegenerative disease with studying cell communication, and I studied cell damage in haemorrhagic stroke for my Ph.D. thesis, looking at how haemoglobin from the blood can alter cell health and communication. I'm now very passionate about understanding the brain, and I can't imagine working in a different field.

Dawn: What is the current focus of your Post Doc research? 

Hannah: After four years of studying stroke, I decided on a change in direction – but still wanted to use patch clamp in my work. I am currently working at the University of Oxford in the lab of Dr. Simon Butt, where we study brain development. I get to use really cool techniques to look at cell communications in the developing mouse brain by combining patch-clamp with laser-activation of cell signaling. We are investigating how certain treatments, such as antidepressants, can modify development and may lead to sensory disorders later in life. 

It's been a steep learning curve going from studying stroke to brain development in different regions of the brain than I am familiar with, but I love widening my neuroscience knowledge, and the techniques I use make it barely feel like work.

Dawn: How do you see art fitting into your life in the future?

Hannah: I really feel I have found "my" craft with embroidery, and I hope to continue it for many years to come. Post-PhD life is very busy, and I sadly have less time to focus on art these days; however, it is still my favorite thing to do in my downtime. I personally love having embroidery in my home, whether it is mine or from other artists, and my pieces I keep for myself tell a tale of my career so far. I hope to build on that and use art as a way to keep in touch with the neuroscience world wherever I end up. 

Dawn: I have noticed a lot of people with PhDs in neuroscience recently have pursued careers in the creative field, like illustration, graphic design, and visual communications. Do you ever wonder if your needlework might take you on a different professional path?

Hannah: It would be a dream to work in visual communications, but unfortunately, I think embroidery is too slow a craft for that! Some of my pieces take upward of 60 hours to complete, which is more suited to art for leisure rather than for professional projects with deadlines, such as in science communication. I love seeing fellow scientists branch out into creative fields and how each person has their own style in conveying information visually. 

That said, I do enjoy writing and creating graphics to communicate my research, and I have always loved public engagement to promote awareness of scientific information to a wider audience. I certainly won't rule out a more creative career – for now, I really enjoy hands-on research and am seeing where the neuroscience winds take me.

Dawn: What are your future plans for Needles & Neurons?

Hannah: Since I have less time to make embroideries these days, my brand has slightly shifted from a (very) small business more towards a hobby in my mindset to take the pressure off and allow it to be compatible with my other work. However, I have no intention of stopping embroidery under the name Needles & Neurons, and I will continue raising funds to support Alzheimer's Research UK – I still have multiple works in progress at any given time; they just take a little longer to complete! I would love to keep up my creative outlet, and maybe one day, when I am settled into a career, I might have a little more time to offer more kits, patterns, and tutorials to engage the next generation of scientists in science art too. 

Above are several examples of biology and neuroscience embroideries by Dr. Hannah Warming.

Exploring the Wonders of the Human Brain: A Journey through Science and Art at the Madrid Book Fair

The 82nd Madrid Book Fair, spanning the duration of two weeks (May 26-June 11, 2023), is welcoming visitors with a multitude of booths representing nearly 1,000 publishing houses across 424 exhibitors. This year's event has undergone modifications aimed at redesigning specific areas to enhance the accessibility of books and alleviate congestion. One noteworthy addition is the implementation of the "shadow project," whereby select sections of the fairgrounds will be covered with tarps. This initiative has been made possible through the support of the Healthy Skin Foundation of the Spanish Academy of Dermatology and Venereology.

Another departure from the Madrid Book Fair tradition is the omission of the customary "Guest Country" designation, which has been replaced by the overarching theme and motto:          

"We're into Science and Letters"  [#DeCienciasYLetras] 

In line with this new approach, exploring scientific literature, many activities are organized to include an established "Science Square" that serves as a collective epicenter of the fair. Among the notable attractions within this area is a projection of a giant brain, coinciding with the Año Cajal, created by CSIC Divulga, provides insights into the intricacies of neuronal functioning.

Recognizing that science permeates our daily lives, the Madrid Book Fair endeavors to bridge the gap between scientific knowledge and the general public. In this context, activities explore diverse manifestations we encounter, like the metadata that impacts cyber algorithms that shape our social networks and our individual and collective identities. Other presentations of contemporary existence, such as emerging artificial technologies, have showcased how art is integrated into our lives through scientific illustrations. To that end, the Madrid Book Fair welcomed esteemed guests, including Alejandro Vergara Sharp, the head of the Conservation Area of Flemish Painting and Northern Schools at the Prado Museum, and José Ramón Marcaida, the Head Scientist of the History of Science Department at the CSIC History Institute. Together, these two experts shed light on the captivating interplay between art and science during the 15th and 16th centuries, revealing key insights into this dynamic relationship. Other experts specializing in diverse fields will offer insights on the intersection of scientific and literary subjects on the pavilion for Science and Universities.

A riveting exhibit at the Madrid Book Fair, introduced above, is the enthralling exhibition that explores one of science's most enigmatic marvels: the human brain. This exhibit dovetails with the Año Cajal and    examines the intricacies and allure of the brain and the exhibition examines the complexity of the human mind. This installation embodies a unique and immersive experience that is captivating to the viewer and is a testament to the symbiotic relationship between science and art.

Art of Neuroscience Award and Scientific American Feature

I am an artist who uses the biography of Santiago Ramón y Cajal and his neuroscience research as the inspiration for my artwork. Earlier this year, my artwork, Dueling Cajals, won an Honorable Mention in the international Art of Neuroscience competition out of the Netherlands. I am honored and speechless to have my artwork featured in Scientific American in an article about the competition. In the article, I share my artwork with the writers and editors (Fionna M. D. Samuels and Liz Tormes) and how the Cajal Legacy at the Instituto Cajal and neuroscience inspire my art about Cajal. 

 

Above my artwork, Dueling Cajals, receives Honorable Mention in the 2022 Art of Neuroscience 

International competition.

My artwork is based on my thorough study of Cajal's life and his scientific drawings, which I conduct in collaboration with leading experts in the neuroscience field at the National Institutes of Health, Bethesda, MD, and Instituto Cajal, Madrid, Spain. I have created over 300 works about Cajal in my ongoing project. My creative project aims to help increase public awareness of the wonders and how the process of drawing can create unique insight and interpretations for scientific research. Overall, my series about Cajal is biographically informative about him and his drawing process.

Me with my primary source references for my work Dueling Cajals: Cajal's Nobel Prize, his original scientific drawing of regenerative nerve cells and his death mask. All of these items are housed at the Instituto Cajal, Madrid, Spain.

Historical Background about Cajal

Santiago Ramón y Cajal (1852-1934) was born in a small town in Spain. His father was a doctor, and Cajal grew up interested in science. He went to medical school, but he also studied biology and physics. He studied the brain using histological staining methods, microscopes, micrographs, and drawing. He discovered how different parts of the brain work. Cajal was also a great teacher and helped train many scientists who would go on to make significant contributions to neuroscience, like Fernando De Castro (arterial chemoreceptors), Rafael Lorente de Nó (audio-vestibular nuclei and system), and E. Horne Craigie (zoologist and author).

Along with Camillo Golgi, Cajal won the Nobel Prize for his work in 1906.

He did his seminal work in the late 1800s and early 1900s. He is known for problem-solving and innovation, like altering and improving the Golgi Black Reaction stain, which allowed him to visualize the nervous system in unprecedented detail. His discoveries continue to be the basis for our understanding of the brain.

One of Cajal's most important contributions was his development of the Neuron Doctrine. This theory states that the nervous system comprises individual cells called neurons. Santiago Ramón y Cajal's work on the neuron doctrine helped establish neuroscience as its scientific discipline.

Cajal, was an absolute genius, he has left a profound impact on neuroscience. He was the trailblazer for the neuron doctrine; his work was like this beacon, guiding our understanding of the brain's mysterious labyrinth. Cajal is just this pivotal force in neuroscience history. Even now, scientists and artists can't help but study and admire the incredible things he's discovered and are mesmerized by the beauty of his drawings.

It's wild to think about how much Cajal's work has shaped the field of neuroscience! His brilliant investigation into the nervous system's anatomy? A total game-changer. It's like he took a paintbrush and reimagined the canvas of our understanding. Because of him, neuroscience became its unique masterpiece, and he paved the way for many discoveries we're still making today. Even modern neuroscientists continue to reference his work, ensuring his legacy lives on for generations.

Cajal's discoveries about the brain's structure and function are like these vibrant colors, leaving a lasting impression on the field. And we're still diving into his work today, using it to make headway in figuring out neurological disorders. It's honestly so inspiring. Cajal's work is like this beautiful testament to the power of science, and it shows how vital curiosity and creativity are when we're chasing after our research.

Conclusion

I have enjoyed making artwork about Cajal's life and histology research. I am honored to have my work receive an Honorable Mention Award in the Art of Neuroscience competition and delighted that it was featured in Scientific American.
