Memory and the septo-hippocampal system
Memory and the septo-hippocampal system
This chapter reviews data on amnesia in humans and other animals. It argues that hippocampal ‘amnesia’ does not result from changes in a particular type of memory and does not depend primarily on effects of delay and context. Relational memory, configural memory, semantic encoding, recognition memory, working memory, temporal buffering, and spatial memory are all shown to fail as an explanation of hippocampal sensitivity of learning and memory. The nature of hippocampal deficits, both in tasks involving memory and those involving innate responses, are more consistent with the view that hippocampal damage removes the capacity to select between strongly competing, conflicting goals by increased avoidance of one of the alternatives — in many memory tasks this adds up to the capacity to eliminate interference of whatever origin.
Keywords: amnesia, hippocampus, relational memory, configural memory, semantic encoding, recognition memory, working memory, temporal buffering, spatial memory
