![]() ![]() In this article I review the evidence indicating that the same brain activity involved in sleep replay associated memory consolidation is responsible for sleep-dependent forgetting. Like memory consolidation, a role for sleep in adaptive forgetting has both historical precedent, as Francis Crick suggested in 1983 that sleep was for “reverse-learning,” and recent empirical support. ![]() Sleep has been shown to be critical for the transfer and consolidation of memories in the cortex. Specifically, most modeling suggests that memories are rapidly acquired during waking experience by the hippocampus, before being later consolidated into the cortex for long-term storage. Current memory models maintain that these two brain structures accomplish unique, but interactive, memory functions. and Karl Lashley’s equipotentiality studies that the hippocampus and cortex serve mnestic functions. ![]() It has been known since the time of patient H.
