Particularly during earlynight nrem sleep when memory reactivation in animals is at its strongest, dream content is very likely to reflect recent learning experiences. A description of memory from the perspective of complex systems may therefore be useful to interpret and understand existing neurobiological data and to plan future research. This memory consolidation, or the process of trace stabilization and strengthening, preferentially occurs during sleep 24. Physiological studies of hippocampal and cortical activity as well as of brainstem neuromodulatory systems demonstrate the statedependence of communication both between and within the neocortex and. By beth israel deaconess medical center, rxpg memorizing a series of facts is one thing, understanding the big picture is quite another. A rat study provides clear evidence that sharp wave ripples, brainwaves that occur in the hippocampus when it is offline, most often during stage four sleep, are responsible for consolidating memory and transferring the learned information from the hippocampus to the neocortex, where longterm memories are stored. The theory of sleeprelated consolidation assumes that new information is somehow reactivated during sleep, with off line reprocessing of traces at distinct levels of memory functioning 3,39. Decoding materialspecific memory reprocessing during. Sep 11, 2017 in order to investigate whether memory reorganization from the learning to the consolidated trace occurred during the off line periods dependent upon either simple passage of time or sleep, or whether the consolidated trace merely manifested itself during retest, we calculated ci within the learning and consolidated patterns during different restingstate periods rs1, rs2, rs3, as well as. In this study, we investigated whether the learned material could be orally reprocessed during sleep talking.
