I received my Ph.D. in Neuropsychology in 1972 from the City University of New York. Since that time, the overarching theme that has guided my research has been to determine the relation between brain activity and cognitive processes  using the event-related brain potential (ERP) as the interface. To accomplish that goal, I have attempted to anchor ERP findings in cognition by using paradigms from cognitive psychology that have proven fruitful in understanding complex cognitive functions. This theme has been played out in all of my studies within a variety of traditional neuropsychological contexts including: 1) normal cognitive development; 2) normal and abnormal aging; 3) language function; 4) memory; and 5) abnormal behavior. Recently, through collaborative efforts with scientists from Neurological Institute, and the Sergievsky Center, I have become involved with three new areas of research, memory function in temporal lobe epilepsy patients, intracranial ERP recording, and functional magnetic resonance imaging (fMRI). Patients with removals of the anterior aspect of the medial temporal lobe provide a means of assessing that region’s impact on memory function, while the recording of ERPs directly from the brain allows one to make inferences as to the brain regions that give rise to the ERPs recorded at the scalp.  The use of fMRI provides a method of more precisely understanding which brain regions are activated by specific cognitive processes. The concomitant use of both ERP and fMRI techniques should allow a more accurate spatio-temporal brain source imaging of a wide variety of cognitive functions.
