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
• Retroactive interference causes forgetting by the competition of two memory engrams
• Forgotten engrams can be expressed or updated by reexposure to training cues
• Artificial reactivation of engram cells rescues interference-induced forgetting
• 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.
