The hippocampus contributes to temporal duration memory in the context of event sequences: A cross-species perspective

Cross-species evidence supports a role for the hippocampus in duration memory. Discrepancies in findings cloud the conditions governing hippocampal involvement. We suggest the importance of considering the hippocampus as a sequence processor. The hippocampus supports duration memory in the context of event sequences. Overlapping hippocampal mechanisms may support memory for duration and order.

The human medial temporal lobe is necessary for remembering durations within a sequence of events but not durations of individual events

Evidence for the incorporation of temporal duration information in human hippocampal long-term memory sequence representations

We demonstrate that multivariate patterns of activity in the human hippocampus during the recognition and cued mental replay of long-term sequence memories contain temporal structure information in the order of seconds. By using an experimental paradigm that required participants to remember the durations of empty intervals between visually presented scene images, our study provides evidence that the human hippocampus can represent elapsed time within a sequence of events in conjunction with other forms of information, such as event content. Our findings complement rodent studies that have shown that hippocampal neurons fire at specific times during the empty delay between two events and suggest a common hippocampal neural mechanism for representing temporal information in the service of episodic memory.

Multivoxel pattern similarity suggests the integration of temporal duration in hippocampal event sequence representations

Hippocampal activity patterns are sensitive to temporal order and duration. Duration sensitivity is not dependant on explicit temporal processing. Findings support a temporal representation of event sequences in the hippocampus.

Perception of impossible scenes reveals differential hippocampal and parahippocampal place area contributions to spatial coherency

Surprisingly little is known about how the brain combines spatial elements to form a coherent percept. Regions that may underlie this process include the hippocampus (HC) and parahippocampal place area (PPA), regions central to spatial perception but …
