Dr. Castañeda investigates plasticity in presynaptic mechanisms that modulate neurotransmitter release during changes in behavior due to neurodegeneration or substance abuse. It is interesting to speculate how fundamental mechanisms that govern learning and memory might serve for compensation in surviving dopamine neurons of the brain compromised by Parkinson's disease and how these same mechanisms might play a role in the sensitization of dopamine neurons by repeated exposure to stimulant drugs.
