Brief interactions spur lasting waves of gene activity in the brain

A new study measured robust changes in brain gene expression for up to two hours after a three-spined stickleback fish encountered another fish.

A five-minute encounter with an outsider spurs a cascade of changes in gene activity in the brain that can last for hours, researchers report in a study of stickleback fish. The research, described in the journal PLOS Genetics, is one of three recent studies - the others conducted in honey bees and mice - to see waves of changes in gene expression in the brain 30 minutes to two hours after contact with an intruder.
