Beyond the Cognitive Map: From Place Cells to Episodic Memory
MIT Press, 1999 - Medical - 420 pages
There are currently two major theories about the role of the hippocampus, a distinctive structure in the back of the temporal lobe. One says that it stores a cognitive map, the other that it is a key locus for the temporary storage of episodic memories. A. David Redish takes the approach that understanding the role of the hippocampus in space will make it possible to address its role in less easily quantifiable areas such as memory. Basing his investigation on the study of rodent navigation--one of the primary domains for understanding information processing in the brain--he places the hippocampus in its anatomical context as part of a greater functional system.
Redish draws on the extensive experimental and theoretical work of the last 100 years to paint a coherent picture of rodent navigation. His presentation encompasses multiple levels of analysis, from single-unit recording results to behavioral tasks to computational modeling. From this foundation, he proposes a novel understanding of the role of the hippocampus in rodents that can shed light on the role of the hippocampus in primates, explaining data from primate studies and human neurology. The book will be of interest not only to neuroscientists and psychologists, but also to researchers in computer science, robotics, artificial intelligence, and artificial life.

In the primate. Lesions of the hippocampus (and adjacent cortical areas) in
primates (particularly humans) cause a profound anterograde amnesia (Scoville

Although there are no recordings of neurons in rodent inferotemporal cortex (Te2
), in the primate inferotem- poral cortex neurons are primarily visual (Desimone et
al., 1985; Tanaka et al., 1991). This suggests that while spatial parameters may ...

because most of the findings on consolidation and retrograde amnesia come
from the primate (particularly, the human) literature, I will discuss them here. (The

We can now turn our attention back to primates: What role does the hippocampus
play in the monkey? In the human? THE PRIMATE EXPERIMENTAL
LITERATURE The monkey experimental literature is more limited than the rat and
While there is evidence showing a differentiation of function for different medial
temporal lobe structures in the primate (e.g. Murray, 1992), most of the primate
studies (both monkey and human) continue to lump these areas together. Thus it
