Webslow wave sleep. Slow wave sleep is marked by high amplitude, synchronized delta activity, usually 0.5-2 Hz in frequency.All of the architecture from earlier sleep phases (vertex waves, POSTS, spindles and K complexes) can be present in slow wave sleep, but usually become somewhat less organized, and often disappear altogether. Sleep spindles are bursts of neural oscillatory activity that are generated by interplay of the thalamic reticular nucleus (TRN) and other thalamic nuclei during stage 2 NREM sleep in a frequency range of ~11 to 16 Hz (usually 12–14 Hz) with a duration of 0.5 seconds or greater (usually 0.5–1.5 seconds). After … See more No sleep spindles have been observed in reptiles and birds so far. In most mammals sleep spindles were described at face value, but the existence of pseudo-spindles invites uncertainty around these observations. … See more Sleep spindles play a crucial role in declarative memory consolidation, however, most studies neglect to control for sex , although … See more

WebJan 1, 2013 · Sleep spindle oscillations consist of waxing-and-waning field potentials at 7-14 Hz, which last 1-3 seconds and recur every 5-15 seconds. In vivo, spindle oscillations are typically observed during the early stages of sleep or during active phases of slow-wave sleep oscillations.
WebSensorimotor rhythm. The sensorimotor rhythm ( SMR) is a brain wave. It is an oscillatory idle rhythm of synchronized electric brain activity. It appears in spindles in recordings of EEG, MEG, and ECoG over the sensorimotor cortex. For most individuals, the frequency of the SMR is in the range of 13 to 15 Hz.
