Hippocampal area CA2 has several features that distinguish it from CA1 and CA3, including
a unique gene expression profile, failure to display long-term potentiation and relative …

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 …

Social memory consists of two processes: the detection of familiar compared with novel
conspecifics and the detailed recollection of past social episodes. We investigated the …

The ability to recognize information that is incongruous with previous experience is critical
for survival. Novelty signals have therefore evolved in the mammalian brain to enhance …

Recent results suggest that social memory requires the dorsal hippocampal CA2 region as
well as a subset of ventral CA1 neurons. However, it is unclear whether dorsal CA2 and …

Oxytocin receptor (Oxtr) signaling in neural circuits mediating discrimination of social stimuli
and affiliation or avoidance behavior is thought to guide social recognition. Remarkably, the …

The concept of cognitive map has been proposed as a way to organize our experiences and
guide behavior across all domains of cognition. The hippocampus has been identified as the …

Social behavior encompasses a number of distinctive and complex constructs that form the
core elements of human imitative culture, mainly represented as either affiliative or …

Synapses between neurons are malleable biochemical structures, strengthening and
diminishing over time dependent on the type of information they receive. This phenomenon …
