Rem sleep and memory consolidation

This may sound surprising as REM is closer to waking than any other phase of sleep. The letter-number test requires attention and encoding. The same number of subjects was trained at 9pm and tested 9am following sleep. Recent studies have demonstrated that salience increases declarative memory performance [13] , [19]. Performed the experiments: KTP. Our sample size was relatively small and limited to early adolescence, ages 10—14, although twice the sample of Prehn-Kristensen et al. Spencer et al. Curr Opin Neurobiol. It is likely that if immediate recall following each presentation was obtained, higher accuracy rates would have been observed. Consolidation represents the processes by which a memory becomes stable. Judgment becomes impaired. Some scientists have argued that the observed differences in learning are not actually due to the lack of REM sleep, but may be due to the animals not being as well rested because they were deprived a portion of their sleep. An increase of Particularly during stage 3 deep sleep , the memories that have been put in the hippocampus short-term memories formed during the previous day are redistributed to the neocortex where they will be long-term memories.

Sections of the brain — the hippocampus, neocortex and amygdala — that are important in memory are active during sleep. The sample population reflected the general school population in this geographic area, although Asians were underrepresented We do not know of any studies that validate this hypothesis.

relationship between sleep and memory

The equal performance at both sessions and between groups on the LN supports the view that equal registration and encoding of the memoranda was comparable at both time points and between groups. Features on this page The Learning Process and Sleep Healthy sleep is essential for optimal learning and memory function.

Other researchers, however, have suggested that any changes in the amount of REM sleep are due to the stress of the task itself, rather than a functional relationship to learning.

sleep and memory retention

Although there are some open questions about the specific role of sleep in forming and storing memories, the general consensus is that consolidated sleep throughout a whole night is optimal for learning and memory.
