More than 50 years of research have led to the general agreement that the hippocampus
contributes to memory, but there has been a major schism among theories of hippocampal …

Serotonin 5-HT2A receptors (5-HT2ARs) are widely distributed in the central nervous
system, especially in brain region essential for learning and cognition. In addition to …

Gamma oscillations (∼ 25–100 Hz) are believed to play a role in cognition. Accordingly,
aberrant gamma oscillations have been observed in several cognitive disorders, including …

Spatial learning requires remembering and choosing paths to goals. Hippocampal place
cells replay spatial paths during immobility in reverse and forward order, offering a potential …

Memory consolidation is the hypothetical process in which an item in memory is transformed
into a long-term form. It is commonly addressed at two complementary levels of description …

People recall more information after sleep than after an equally long period of wakefulness.
This sleep benefit in episodic memory has been documented in almost a century of …

Durations are defined by a beginning and an end, and a major distinction is drawn between
durations that start in the present and end in the future ('prospective timing') and durations …

Hippocampal replays are episodes of sequential place cell activity during sharp-wave ripple
oscillations (SWRs). Conflicting hypotheses implicate awake replay in learning from reward …

Our daily lives unfold continuously, yet when we reflect on the past, we remember those
experiences as distinct and cohesive events. To understand this phenomenon, early …

Sleep has been implicated in both memory consolidation and forgetting of experiences.
However, it is unclear what governs the balance between consolidation and forgetting. Here …
