ABSTRACT
This review is our tribute to Carlos Beyer Flores PhD, a pioneering investigator in the field of neuroendocrinology who had an outsized influence both locally in his laboratories at the National Autonomous University of Mexico (Institute for Biomedical Research), at the Mexican Institute for Social Security, at the Autonomous Metropolitan University (in Mexico City); in Tlaxcala, where he established a laboratory involving a collaboration between the Center for Research and Advanced Studies of the National Polytechnic Institute and the Autonomous University of Tlaxcala and in the US at the Institute of Animal Behavior, Rutgers University, Newark, N.J. His influence extended even more broadly via his inspiring talks and courses around the world. We are privileged to count ourselves among his many students and colleagues and hold an unredeemable debt to him for the gift of training in scientific rigor, the art of experimental design and the joy of discovery. He was a pervasive and ubiquitous modulatory influence, much like one of his favorite molecules, the amino acid transmitter gamma-aminobutyric acid (GABA).
