[HTML][HTML] Hippocampal “time cells” bridge the gap in memory for discontiguous events
CJ MacDonald, KQ Lepage, UT Eden, H Eichenbaum - Neuron, 2011 - cell.com
The hippocampus is critical to remembering the flow of events in distinct experiences and, in
doing so, bridges temporal gaps between discontiguous events. Here, we report a robust …

Dynamics of hippocampal spatial representation in echolocating bats
N Ulanovsky, CF Moss - Hippocampus, 2011 - Wiley Online Library
The “place fields” of hippocampal pyramidal neurons are not static. For example, upon a
contextual change in the environment, place fields may “remap” within typical timescales …
