The immune system affects – and even controls – social behavior, a new study has found. Researchers discovered that blocking a single type of immune molecule made mouse brains go hyperactive and caused abnormal behavior; restoring it fixed both. The discovery could have enormous implications for neurological conditions such as autism and schizophrenia. (1) It…

By tinkering with the gut’s bacterial residents, scientists have changed the behavior of lab animals and small numbers of people. Microbial meddling has turned anxious mice bold and shy mice social. Rats inoculated with bacteria from depressed people develop signs of depression themselves. And small studies of people suggest that eating specific kinds of bacteria…

Far-reaching neurons in the central amygdala, the location of fear memory in the brain seen here in red (right), directly contact neurons in the…
