Whereas we understand life as a steady movement, our brains mechanically break recollections into distinct moments.

How does the mind determine the place one reminiscence ends and one other begins?
To discover this, Baldassano and his group performed a brain-scan experiment utilizing useful magnetic resonance imaging (fMRI). Volunteers listened to narratives involving numerous eventualities, resembling a enterprise deal, a proposal, and a breakup, whereas their mind exercise was recorded. The analysis centered on adjustments within the medial prefrontal cortex (mPFC), a mind area concerned in processing ongoing occasions.

This highlights how versatile reminiscence is and the way our consideration shapes what we keep in mind. David Clewett, assistant professor of cognitive psychology at UCLA, famous that the findings present we’ve got vital management over how we interpret and keep in mind occasions.
