Justin S. Rhodes received his Ph.D. from the University of Wisconsin-Madison. He was a postdoctoral fellow at Oregon Health & Science University and an instructor at Lewis & Clark College. He is presently an Assistant Professor in the University of Illinois Department of Psychology, Neuroscience Program, Institute for Genomic Biology and a full-time faculty member in the Beckman Institute NeuroTech Group. His fields of research interests are behavior genetics and neurobiology of motivation and addiction, and effects of exercise on brain function and cognition using mice as a model organism.
Dr. Rhodes is broadly interested in exploring how genes and environment affect voluntary behavior. His early research involved a selective breeding experiment in which mice were bred to display extremely high levels of voluntary physical exercise on running wheels. Results of pharmacological studies and brain imaging suggested that the neural basis of high running shared many features in common with that of motivation to self-administer drugs of abuse. One of the main focuses of his current research program is to study the extent to which the physiological bases of natural forms of motivation (such as motivation for food, sex or exercise) overlap with drug-induced motivation.
Current projects include:
- Using high-resolution brain imaging (immunohistochemical detection of c-Fos and Zif268) to identify brain regions that become activated when mice are placed into an environment where they had previously received a drug of abuse and comparing these responses to when a natural reward, such as food or exercise, is used for the conditioning.
- Continuing to develop mouse models that self administer intoxicating doses of ethanol to study the neural and genetic basis of excessive alcohol drinking.
- Using selective breeding to develop lines of mice that display extremely high levels of physical activity in their home cages to study effects of genetic hyperactivity on learning and memory, aging, stress, responses to drugs of abuse and more generally to identify the genetic basis of hyperactivity and relationship to drug addiction.
- Studying the effects of exercise on the morphology and physiology of the mouse brain to understand how exercise can improve learning and memory with an emphasis on relating the animal research to current human findings. Techniques include pharmacology, brain imaging, gene expression profiling, selective breeding, comparisons across standard inbred strains, and quantitative trait locus (QTL) mapping.
Dr. Rhodes' research is currently funded by NIH/NIAAA.
