Forgetting as a form of adaptive engram cell plasticity

TJ Ryan, PW Frankland - Nature Reviews Neuroscience, 2022 - nature.com
One leading hypothesis suggests that memories are stored in ensembles of neurons (or
'engram cells') and that successful recall involves reactivation of these ensembles. A logical …
