Brain's activity map makes stable 'fingerprint'



illustration of brain connection map


Neuroscientists have found that they can identify individuals based on a coarse map of which brain regions "pair up" in scans of brain activity.
The map is stable enough that the researchers could pick one person's pattern from a set of 126, by matching it to a scan taken on another day.
