A new NIH grant will allow Virginia Tech researchers to explore the mechanisms of social memory in the hippocampus.
Serotonin-producing neurons in the brainstem release serotonin throughout the brain during moments of novel social encounters. The release of serotonin stimulates neurons in the medial septum via a subtype of serotonin-sensitive receptor molecules. Blocking the release of this receptor molecule prevents the formation of new social 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.
Ventral CA1 neurons in the hippocampus store memories of acquaintances, a new study reports.
In order to make informed choices, rats replay past experiences, a new study reports.
Researchers report emotions directly influence the neurological processes associated with memory and learning.
CA2, a small region of the hippocampus, is essential for social learning, a new study reports.
