Hippocampal time cells carry a record of recent experience by firing during a circumscribed
period of time after a triggering stimulus. Different cells have “time fields' at different delays
up to at least tens of seconds. The observation that time fields representing events further in
the past are wider supports the hypothesis that the more distant past is recorded with less
resolution. However, previous studies have analyzed time fields averaged over trials,
leading to the possibility that this could be a trial-averaging artifact. We analyzed single-unit …
