BBC NEWS | Health | 'People-person' brain area found: "Scientists say they have located the brain areas that may determine how sociable a person is.

Warm, sentimental people tend to have more brain tissue in the outer strip of the brain just above the eyes and in a structure deep in the brain's centre.

These are the same zones that allow us to enjoy chocolate and sex, the Cambridge University experts report in the European Journal of Neuroscience.

The work suggests that some people may get a similar buzz from being sociable.

It could also lead to new insights into psychiatric disorders where difficulties in social interaction are prominent, such as autism or schizophrenia."
