Baxter P. Rogers, Ph.D.
I study the structure and function of the brain. I am particularly interested in methods of measuring the timing of functional MRI signals and the correlations between them, and in applications of these methods to the study of neurological and mental disorders.
I am currently involved in a series of studies of hippocampal structure and function in epilepsy and psychosis, using ultra high field MRI with new methods of measuring functional connectivity and statistical approaches appropriate for the large data sets involved. Recent methodological work is focused on understanding dynamic variation in functional connectivity over short time scales (minute to minute).
