Faculty Research Lab
Hartman Behavioral Neuroscience Lab
This lab's research is broadly concerned with promoting healthy brain aging/increasing an individual's "health-span," and generally falls into 1 of 3 overlapping categories: 1) characterizing models of neurodegeneration; 2) preventing neurodegeneration and/or increasing the brain's resiliency; and 3) characterizing the effects of plant-based compounds (phytochemicals) in the brain.
