Heterogeneity within classical cell types is the rule: lessons from hippocampal pyramidal neurons
MS Cembrowski, N Spruston - Nature Reviews Neuroscience, 2019 - nature.com
The mechanistic operation of brain regions is often interpreted by partitioning constituent
neurons into 'cell types'. Historically, such cell types were broadly defined by their …

How development sculpts hippocampal circuits and function
R Cossart, R Khazipov - Physiological Reviews, 2022 - journals.physiology.org
In mammals, the selective transformation of transient experience into stored memory occurs
in the hippocampus, which develops representations of specific events in the context in …

Hippocampal CA2 sharp-wave ripples reactivate and promote social memory
The consolidation of spatial memory depends on the reactivation ('replay') of hippocampal
place cells that were active during recent behaviour. Such reactivation is observed during …

REM sleep-active hypothalamic neurons may contribute to hippocampal social-memory consolidation
The hippocampal CA2 region plays a key role in social memory. The encoding of such
memory involves afferent activity from the hypothalamic supramammillary nucleus (SuM) to …

The hippocampus converts dynamic entorhinal inputs into stable spatial maps
The medial entorhinal cortex (MEC)-hippocampal network plays a key role in the
processing, storage, and recall of spatial information. However, how the spatial code …

Linking social cognition to learning and memory
Many mammals have evolved to be social creatures. In humans, the ability to learn from
others' experiences is essential to survival; and from an early age, individuals are …

Immunohistochemical field parcellation of the human hippocampus along its antero-posterior axis
E González-Arnay, I Pérez-Santos… - Brain Structure and …, 2024 - Springer
The primate hippocampus includes the dentate gyrus, cornu ammonis (CA), and subiculum.
CA is subdivided into four fields (CA1-CA3, plus CA3h/hilus of the dentate gyrus) with …
