The study reports repeated social interactions tune visual neurons in the face processing network to enable consistent and rapid rapid recognition of familiar faces.
Researchers report they are able to see alterations in gene expression up to two hours after a stickleback fish interacts with an intruder. They speculate the changes in gene expression and chromatin modification could help set up the brain to respond to future threats. The study appears in PLOS Genetics.
Researchers report levels of social impairment remain stable for those with psychosis, years after their first hospitalization.
