Dr. Christopher Jenney

Brasfield

Dr. Jenney is the principal investigator of the Behavioral & Nutritional Neuroscience Laboratory. The Laboratory’s research focus is investigating dietary nutrients’ effect on individual differences in vulnerability to addiction and addiction-like behavior. With the current opioid epidemic, it is important to recognize that many people are more susceptible than others to drug addiction. Dr. Jenney’s team studies the biology of these individual differences and seeks to identify nutritional influences, such as nutrient deficiencies, which make susceptible individuals more vulnerable. Using animal models of addiction, the Laboratory studies the behavioral differences which emerge after dietary nutrient deficiencies and supplementation. The biological and molecular bases for this behavior are then studied in vitro to elucidate the genetic and neurological mechanisms underlying vulnerability to drugs of abuse.

The primary emphases of the Laboratory are iron and omega-3 fatty acids deficiencies and the role supplementation with long-chain omega-3 fatty acids (fish oil, EPA, DHA) have on alleviating vulnerability to drugs of abuse. With this knowledge, the ultimate goal is to develop nutritional interventions that dieticians, therapists and psychiatrists can utilize to help recovering addicts avoid relapse and remain drug-free, productive members of society.
