A fundamental property of many associative memory networks is
the ability to decorrelate overlapping input patterns before infor-
mation is stored1­5
. In the hippocampus, this neuronal pattern
separation is expressed as the tendency of ensembles of place cells6
to undergo extensive `remapping' in response to changes in the
sensory or motivational inputs to the hippocampus7­13
. Remap-
ping is expressed under some conditions as a change of firing rates
in the presence of a stable place code (`rate remapping')14
, and
under other conditions as a complete reorganization of the hippo-
