Sleep Spindles

Stage 2 is where we spend the majority of the night while sleeping. Typically, more time is spent in stage 2 sleep than in light sleep, deep sleep or dream sleep. It would seem that if so much time were spent in this stage of sleep that some very important function must be served. It has not been so easy, however, to discover just what this function is. In my last post, I discussed the beneficial effects of a brief nap on neurocognitive functioning. Recent research indicates that some very important brain activities are carried out when sleep spindles are occurring, whether during nighttime sleep or daytime naps.
