Undergraduate Neuroscience

My research interests include the neuroanatomical and neuropharmacological basis of timing and time perception in the seconds-to-minutes range. This work is related to the development of the striatal beat-frequency model of interval timing as well as mode-control models of temporal integration and attentional time-sharing in humans and other animals. Current work focuses on the use of molecular and ensemble-recording techniques designed to identify the basic properties of interval timing and decision making in cortical-striatal circuits as well as fMRI to examine temporal processing deficits in selected clinical populations (e.g., Parkinson's disease and schizophrenia). A second line of research uses animal models to focus on developmental periods of dietary choline sensitivity that provide an ontogenetic mechanism for regulating memory capacity and precision in adulthood as well as inoculation against age-related impairments in spatial and temporal cognition.
