"Time Cells" May Bridge The Temporal Gap In Memory

Dr. Eichenbaum and colleagues developed an innovative task that required rats to distinguish sequences of two events that were separated by a time delay. The task required the rats to remember the initial event in order to respond appropriately to the second event and receive a reward. The researchers recorded hippocampal neural activity as the rats completed the tasks...The researchers observed that activity in the hippocampus robustly represented sequential memories and that certain cells became activated at successive moments during the empty gap that occurred between the two events. more
