Our research program aims to determine the neural basis for spatial cognition, decision-making, and episodic memory. Recent projects have focused primarily on examination of multiple single-unit recordings made in freely behaving animals. Our most recent work concerns recordings made in the parietal cortex, hippocampus, subiculum, and premotor cortex in rats performing either a multiple-T working memory task or executing traversals of differently shaped spiral paths. One new project will examine the activity patterns of basal forebrain neurons during performance of a task demanding dynamic allocation of attentional resources.
