Macho' switch in the brain that makes men aggressive and more competitive is pinpointed for the first time

The 'macho' switch in the brain which makes men aggressive has been discovered by scientists.

And the brain circuit could explain how some animals are able to become alpha males and exert control over others, the study found. 

Researchers found stimulating the switch significantly boosted a mouse's chance of winning aggressive encounters and moving up the social hierarchy.

The discovery could lead to brain training to boost the performance of athletes, said the researchers.

It also offers hope of developing drug targets for pathological aggression - which is a component in Alzheimer’s, autism, bipolar disorder and schizophrenia.
