Two Paths Diverged In The Brain, Ray Guillery Chose The One Less Studied

Ray Guillery profoundly affected my work as a theorist studying the neocortex. What I treasured about Ray was that he didn't just report his experimental findings, he promoted bold new interpretations of them. He challenged conventional wisdom, and, therefore, challenged all neuroscientists to think differently. In this essay, I describe one of Ray's bold ideas, the critical role of the thalamus in how information flows from region to region in the neocortex. This article is protected by copyright.
