Abstract
Sleep deprivation has been found has been found to negatively affect cognitive fitness, primarily attention (e.g. Durmer& Dinges, 2005) and several aspects of memory (e.g. Chee et al., 2006). REM sleep has been primarily studied and it has been found that it plays a strong role in cognitive fitness (e.g. Hornung, Regen, Danker-Hopfe, Schredl, & Heuser, 2007). However, there is a phenomenon in NREM sleep called a sleep spindle, which is an oscillatory brain activity that occurs in Stage 2 of NREM sleep meant to keep a sleeping individual in a state of tranquility by inhibiting brain processing (Rechtschaffen, Kales, 1968). It has been found that these sleep spindles can have an effect on cognitive fitness (e.g Seeck-Hirschner et al. 2012) but many studies are either found sleep spindle data as a side note or only looked at a small portion of the population. The specific effect of sleep spindles and NREM sleep on cognitive fitness could potentially provide more specific information on the purpose of sleep spindles and NREM sleep. This experiment will use the UNRAVEL task used by Altmann, E. et al. (2014) and Hambrick, & Altmann, (2014) to measure cognitive fitness.
