Quizplus · Accepted Answer

Sleep spindles are a defining characteristic of Stage 2 sleep, which is characterized by slower heart rate and breathing, lower core body temperature, and a decrease in overall brain activity. During this stage, the brain also undergoes bursts of activity called K-complexes, which serve to suppress external stimuli in the environment and promote overall sleep stability. Sleep spindles are believed to play a role in consolidating memory and learning processes.
