The Relationship Between Non-REM Sleep and Cognitive Fitness : A Proposed Study
MetadataShow full item record
Research has shown that sleep can affect cognitive function. Sleep deprivation can reduce cognitive function in many areas. REM sleep has been found to affect both memory and attention. NREM sleep has been found to affect memory, and the sleep spindles that occur during NREM sleep show mixed results. Eighteen participants in a within-groups study will be recruited and spent the night in the sleep lab. During the night the time they will spend in NREM sleep and the amount and density of their sleep spindles will be measured and compared to the participants’ scores on the UNRAVEL task which, is meant to measure cognitive fitness. We hypothesize that participants who spend more time during crucial sleep stages and who have more sleep spindles would perform better on the UNRAVEL task the morning after being measured.
