A specialized area of the mouse brain called the SuM specializes in detecting novel experiences. Within this brain area, responses to social novelty, or experiences related to unknown individuals, were segregated from those related to unfamiliar places, before being sent to areas of the brain associated with memory.
In order to make informed choices, rats replay past experiences, a new study reports.
Researchers report specific alterations in signaling circuits associated with memory can induce an abnormal response in neurons, which is linked to the aging process and cognitive decline.
Study documents how CaMKII acts during synaptic plasticity, providing clues about the molecular signals that regulate memory formation.
Pyramidal cells in the CA2 region of the hippocampus are responsible for storing critical timing information.
Researchers use optogenetics to study impairment to the CA2 region of the hippocampus.
Researchers use virtual reality to discover how the brain assembles contextual memories.
A new study reports the CA2 region of the hippocampus controls both higher order cognition, like social memory, and instinctual behaviors, such as aggression. The findings could shed light on why abnormal social behaviors may occur in schizophrenia and other psychiatric illnesses.
