Sleep: much is known about the sleep process. Restore: problem: as we age rem sleep declines. Organize the brain: rem sleep may set up young brains, which is why babies spend so much time in rem sleep. Re-program our brain: rem sleep is i(cid:374)(cid:272)orporati(cid:374)g the day"s i(cid:374)for(cid:373)atio(cid:374) i(cid:374)to the (cid:271)rai(cid:374) Consolidate memories: study: strengthening individual memories by reactivating them during sleep. Transformation of memory item into a long- term form. Period of sleep between encoding and retrieval can benefit memory storage. Direct effect of sleep on consolidation of memories is still unclear. Image of an object paired with a sound. Object appears at the center of screen; participants place it in the original location.
