SUMMARY:The Contrasting Roles of the Hippocampus &amp\; Amygdala in Memory

DESCRIPTION:The hippocampus and amygdala are both members of the medial te
 mporal lobe memory system but represent and store information about very d
 ifferent aspects of the environment and do so in very different ways. The 
 rodent hippocampal formation constructs a spatial representation of the lo
 cal environment which can be used to identify the animal's current locatio
 n\, to remember events that happened there in the past\, and to navigate t
 o desirable locations in that environment. Spatial cells found in the hipp
 ocampal formation represent the animal's location (place cells)\, its curr
 ent heading direction (head direction cells)\, the metric of the environme
 nt (grid cells)\, and the animal' s distance from boundaries of the enviro
 nment (boundary vector cells). In contrast\, the rodent amygdala represent
 s events of ethological salience and generates an active memory trace of t
 heir recent occurrence. I will report unpublished results describing selec
 tive cellular responses to conspecifics\, foods\, and a familiar environme
 nt.  At the end of my talk\, I will suggest ways in which these anatomical
 ly-connected temporal lobe memory systems might interact.\n\n
