Research Interests
I am interested in human episodic memory for verbal, visual and spatial
information. To study this general problem, I conduct experiments that
measure behavioral and electrophysiological responses during memory
tasks, and develop computational models to explain the resulting data.
Our lab is one of several in the world studying the electrophysiological
responses of neurons through direct intracranial electroencephalographic
(iEEG) recording from the living human brain. Such recordings can be
obtained from epilepsy patients who have had electrodes surgically implanted
on the cortical surface of the brain or through the medial temporal
lobes (including hippocampus) as part of the clinical process of localizing
seizure foci. By analyzing how brain activity, including the responses
of individual neurons, correlates with task variables, we are able to
study the neurophysiological basis of memory with a high degree of spatial
and temporal resolution. Current projects include studies of spatial
navigation using a virtual taxi driver game, and computational modeling
of the role of temporal context in visual and verbal memory.
