BIO 337 Lecture Notes - Lecture 13: Sleep Spindle, Delta Wave, Field Recording
Document Summary
Stage 2 - sleep spindles - fast burst of activity. Sleep-dependent memory consolidation: slow waves and spindles. Possible influences of sleep on memory sleep -dependent improvement in a declarative memory task depends on part on motivation and expectation of future retrieval testing. Experiment: told they were going to be tested vs not told before and after sleep. Those who were told they were going to be tested - better recall. Correlation between the amount of sws they had and the % recall. Typically during lighter stages, but also present in sws. Had more spindles when told they were going to be tested. 11 am - taught task (shown stimulus tree, with a short gap between cue. R to remember it) - mixed in between other stimuli (if f = forget) Nap & no-nap - no difference in f-words. R-words did 2x as well with nap. Difference between r-f - better with nap.
