The researchers also found that most participants were likely to increase their positive opinion of a song if the experts also liked it, and lower their rating of a song if the experts didn't like it. This shift in opinion was reflected in ventral striatum activity.

"It seems that not only are some people more influenced by the opinions of others, but by looking at activity in the brain, we can tell who those people are," study author Chris Frith, of the Wellcome Trust Centre for Neuroimaging at University College London, England, said in the news release. - (HealthDay News, June 2010)
