Attention Linked to Specific Brain Regions
March 29, 2007
Researchers have found that the signal in the brain that tells someone to pay attention when they spot a snake in the grass originates in a different part of the brain than signals recognizing a snake at the zoo. The work, which could have implications for treating attention deficit disorder (ADD), is the first concrete evidence that two radically different brain regions--the prefrontal cortex and the parietal cortex--play different roles in these different modes of attention.
