In recent years it has become clear that feeding peptides, which fluctuate as a function of metabolic status, act in brain reward regions to regulate feeding and addictive behavior. Research in the Davis lab is focused on detailing the impact of feeding peptides on cellular, neurochemical and behavioral processes that contribute to addictive behavior(s). In general work from our lab has demonstrated that feeding peptides that stimulate food intake augment the motivation to obtain palatable food and drugs while those that attenuate feeding decrease these parameters. Feeding peptides achieve this regulation through action in brain reward circuits. Current projects are focused on detailing the ability of binge feeding behavior or bypass surgery, and subsequent changes in feeding peptides, to impact attention and motivation for palatable food and drugs of abuse. 

Biographical Information

Jon Davis, Assistant Professor in IPN, received his B.S. in Biology from Maryville College, Maryville, Tennessee in 1997. He then received a PhD in 2005 from the University of Cincinnati College of Medicine, Department of Cell Biology & Anatomy, Cincinnati, Ohio. From 2005-2010 he did postdoctoral work at the University of Cincinnati within the obesity research center. He then went on to become a research scientist within the Department of Psychiatry & Behavioral Neuroscience at University of Cincinnati. In 2014, he was appointed to the faculty as an Assistant Professor at Washington State University, Pullman, WA.
