Forgetting unwanted memories in sleep

Cairney SA, Horner AJ

Trends in cognitive sciences, 2024

Abstract

Memories are sometimes best forgotten, but how do our brains weaken unwanted details of the past? We propose a theoretical framework in which memory reactivation during sleep supports adaptive forgetting. This mnemonic rebalancing underpins the affective benefits of sleep by ensuring that our memories remain aligned with our emotional goals.
