Loss of placental hormone linked to brain and social behavior changes
Preterm birth has been shown to increase the risk of autism spectrum disorders and other developmental problems, particularly in males. The more premature a baby is, the greater the risk of either motor or cognitive deficits. ...

From imaging neurons to measuring their true activity
When neurons communicate with each another, they transmit—or "fire"—small electrical impulses called action potentials or spikes. These action potentials are the fundamental units of information processing in the brain. ...
