A visit to any of these towns -- as explained by people who have lived in or visited them -- will set you apart from your fellow wandering Americans.
To investigate this, Nathaniel Heintz and his colleagues at the Rockefeller University in New York City activated neurons that are sensitive to the hormone oxytocin in the medial prefrontal cortex of the mouse brain.
This did not affect males' sociality, but did reduce anxiety-related behaviours.
In females, however, it made the animals more social without lowering anxiety-related behaviours.
The female mice also had more of a key stress hormone in the brain, which probably blocked the anti-anxiety effects of oxytocin that were seen in males.
