Researchers Identify False Memories with Brain Scans
|
Patterns of electrophysiological activity in the brain may be used to distinguish false memories from real ones, shows a report published in November's Psychological Science.
Researchers examined intracranial electroencephalographic recordings from 52 epileptic patients while they performed a task in which they studied and later free recalled a series of vocabulary words. They found that a brain wave called the gamma rhythm was activated in a distinct pattern in the hippocampus and prefrontal cortex of the brain both when patients studied a vocabulary word and when they recalled it. When patients accidentally named a word that had not been on their vocabulary list, this pattern of brain waves was not observed. The findings provide better insight into the formation of memories--which may help guide doctors in providing the least harmful surgery to epileptic patients, who often elect to have brain surgery to remove areas of the brain where seizures originate.
