WebbSlow oscillations are slowly changing (0.8 Hz) brain rhythms that are observed over many regions in the cortex. Spindles have a far faster oscillation at ∼10–15 Hz. Spindles are generated in the thalamus and form a thalamocortical loop during SWS. Sharp wave–ripples are generated in the hippocampus and have a frequency of 100–300 Hz.
