Brains, Beasts, and Evolution

Have you ever wondered how the intricate tapestry of animal behavior and cognition has evolved over millions of years or how the nervous system has helped to support some of the unique behaviors we see in other species? I for sure have and so while I was trying to get my fix, I stumbled across the annual meeting of the J.B. Johnston Club for Evolutionary Neuroscience and it happened to be around the corner from the Field Museum, which everyone knows is my favorite place on earth! So I just had to go and I got to admit,  I was pleasantly surprised! In fact, I'm still buzzing from the incredible insights and discussions I experienced at this meeting! 

While, admittingly, I was a little hesitant to attend a scientific meeting again (boy has it been many years since I wore a tie), I reached out to the meeting organizers and they assured me that this meeting is unlike others I attended in my youth.This meeting offered a more casual and welcoming atmosphere and a much smaller size than the often overwhelming scientific conferences. Anyway, I am happy to report that it didn't disappoint! 

This annual gathering of the JBJC as everyone seemed to be calling it, brings together some of the brightest minds in comparative and evolutionary neurobiology, with a strong focus on students and trainees as well as young faculty, creating what was really a vibrant forum for the exchange of cutting-edge scientific information.

The J.B. Johnston Club, is named after the pioneering neuroanatomist John Black Johnston, who dedicated his life to unraveling the mysteries of brain evolution across species. Their annual meetings is a two day event (Day 1 a Karger sponsored Workshop in Evolutionary Neuroscience; Day 2 the Annual meeting) and a veritable treasure trove of fascinating presentations, thought-provoking discussions, and opportunities to connect with fellow neuroscience enthusiasts.

One of the highlights of the meeting for me was the Karger Workshop in Evolutionary Neuroscience, which was a one-day symposium style event, featuring carefully selected speakers presenting on a specific topic. This year the topic was on mapping biological diversity and the importance of imaging contributions to the field. The depth and breadth of knowledge shared during this workshop was truly mind-blowing. From the intricate neural circuits of tiny insects to the complex cognitive abilities of marine mammals, every presentation offered a new perspective on how brains have evolved to meet the challenges of different environments. 

The second day of the meeting was equally captivating, with members presenting their latest research. What struck me most was the emphasis on ideas rather than just data. The presenters encouraged lively discussions, challenging us to think critically about the evolutionary processes shaping neural systems.

During a coffee break, I had the pleasure of chatting with Dr. Muhammad Spocter, a biological anthropologist who has worked on a wide range of species and is the current PEO of the society. His enthusiasm for the field was contagious! To quote Dr. Spocter; "This is a scientific family, a community and it's just so liberating to meet others with similar questions about animal behavior and brain evolution. The insights you'll gain here will forever change how you view the natural world and our place within it. "

As I sat back to the next series of talks, Dr. Spocter's words resonated deeply with me, highlighting the importance of this work and made me me even more curious to understand the neural underpinnings of complex behavior in other animals, like my little Tabby cat (Lulu) at home.

Throughout the meeting, I found myself engaged in fascinating conversations with researchers studying everything from the navigation abilities of migratory birds to the social cognition of primates. The diversity of topics and approaches was truly astounding, reflecting the club's commitment to inclusivity and interdisciplinary collaboration. One particularly memorable presentation explored the evolution of the corpus callosum in placental mammals. Learning how this crucial brain structure, which connects the two cerebral hemispheres, first appeared in our distant ancestors and has since varied in size across different species, gave me a new appreciation for the complexity of brain evolution.

Another talk delved into the convergent evolution of certain neural features in distantly related species, reminding us that similar environmental pressures can lead to comparable solutions in brain organization, even in very different animals.

For students and early-career researchers, the J.B. Johnston Club offers an incredibly supportive environment to present ideas and receive feedback from leaders in the field. The atmosphere is collaborative rather than competitive, fostering the kind of open exchange of ideas that drives scientific progress. 

Even if you're not a professional neuroscientist, these meetings offer a unique opportunity to peek behind the curtain of cutting-edge research in evolutionary neuroscience. The presenters are adept at making complex concepts accessible to a general audience, and the passion they bring to their work is truly infectious.

If you're intrigued by the prospect of exploring the evolutionary history of brains and behavior, I strongly encourage you to check out the J.B. Johnston Club's website at https://www.jbjclub.org for more information about their upcoming meetings and how to get involved.

Whether you're a student, faculty member, or simply a curious member of the public, attending a J.B. Johnston Club meeting is sure to expand your horizons and deepen your appreciation for the incredible diversity of animal brains and behaviors. Who knows? You might just find yourself inspired to embark on your own journey of discovery in the fascinating world of evolutionary neuroscience!
