The bottom panel illustrates the overall firing rate of the cell as a function of position. Control by an internal sense of direction carried across environments. Rats require a fixed point of entry to solve place tasks in an enclosed Morris milk maze. Presented at the Animal Behavior Society meeting in Washington, D.C. , June 21-25, 1997. Neuropsychological investigation of hippocampal bases for spatial memory.
Subjects recall positions of objects from familiar and novel views of a virtual space.
Novel viewpoints require an allocentric representation, and poor performance by a hippocampal patient implicates the hippocampal formation in such representations. Crossmodal spatial attention. Using a virtual environment, we are able to examine the integration of auditory and visual information in the classic 'cocktail party' effect. By removing or disrupting a modality, it's individual contribution to performance can be investigated. Over-ruling prepotent responses.
