Weizmann Institute scientists discover that spontaneously
emerging brain activity patterns preserve traces of previous cognitive activity
What if experts could dig into the brain, like
archaeologists, and uncover the history of past experiences? This ability might
reveal what makes each of us a unique individual, and it could enable the
objective diagnosis of a wide range of neuropsychological diseases. New
research at the Weizmann Institute hints that such a scenario is within the
realm of possibility: It shows that spontaneous waves of neuronal activity in
the brain bear the imprints of earlier events for at least 24 hours after the
experience has taken place.
