Evidence that memories are consolidated during sleep
...ve regions of the brain are involved in processing memories
during a particular form of sleep, called slow-wav..., investigators have reported the possibility that memories
are consolidated during sleep by looking at reverberations, but they only looked in the hippocampus ...
Brain reverberations during sleep
...this may support a mechanism to recall and amplify memories
until they are effectively stored. On the basis of differences observed between REM and slow-wave sleep in this and previous studies, the authors propose that the two phases of sleep play separate and complementary roles in memory consolidation. Thus...
