Fight or flight gets joined by f—, pee, & poop


Just a few days ago, I wrote a post about a very unusual occurrence: a serious change in a fundamental piece of neuroanatomy. To recapitulate, Jean Francois Brunet and his colleagues, including lead author Isabel Espinosa–Medina, used a modern molecular approach to show that the autonomic motor neurons in the sacral cord share their characteristics with the sympathetic motor neurons in […]

A revolution in Neuroanatomy!


There has been a revolution in the unlikeliest of disciplines! Neuroanatomy! Yes neuroanatomy – so cut and dry – has been seriously altered by new research. The textbook world of neuroanatomy turned upside down yesterday. A team led by Jean François Brunet of INSERM in Paris has made the audacious proposal that the autonomic outflow of the sacral cord is […]

I just finished teaching Pritzker Medical students (Class of 2015). Once again, it was fun; I learned things and had new thoughts. Teaching is indeed learning.   Today I want to share a recent teaching joy. Pritzker students gathered together on their own initiative to explore caloric testing, which I had talked about in class but never included in laboratory […]

It’s true. I’m a Neuro-freak.


This morning, Diana Keat, a NeuroMOOC student and friend texted me about a story on NPR’s The Takeaway that was about air conditioning as a necessity. As some of you may know from a previous post, the neurobiology of heat waves is one of my pet topics. Mammals have no way to actively cool themselves aka to “refrigerate” their bodies. We can heat ourselves very […]

Can rats feel socially rejected?


Three years ago, an incoming University of Chicago student named Haozhe Shan emailed me asking for an opportunity to work in my laboratory. His letter was well written and demonstrated a focussed and specific interest in social neuroscience. I agreed to talk with him and immediately liked him. Even prior to taking a single college class, he had a knowledge of psychology […]
