Neuroscientists successfully test theory that forgetting is actually a form of learning https://medicalxpress.com/news/2023-08-neuroscientists-successfully-theory.html
Adaptive expression of engrams by retroactive interference https://www.cell.com/cell-reports/fulltext/S2211-1247(23)01010-0
Highlights
âą Retroactive interference causes forgetting by the competition of two memory engrams
âą Forgotten engrams can be expressed or updated by reexposure to training cues
âą Artificial reactivation of engram cells rescues interference-induced forgetting
âą Interference is an active process that requires the activation of the suppressed engram
these findings indicate that retroactive interference modules engram expression in a manner that is both reversible and updatable. Inference may constitute a form of adaptive forgetting where, in everyday life, new perceptual and environmental inputs modulate the natural forgetting process.
