 ====== Sleep spindles ======
-Sleep spindles represent an oscillating electrical potential in the brain. They have a characteristic frequency of 11–16 Hz (usually 12–14 Hz in healthy adults) and last from one to several seconds in duration[(:cite:17557422>{{pmid>17557422}})]. On scalp electroencephalography (EEG), spindles are seen as sinusoidal waves that often have a fusiform or “crescendo-decrescendo” morphology[(:cite:14573378>{{pmid>14573378}})].

+-8 sec and are maximal over Cz. Sensitivity 500 µV peak-to-peak, LFF 0.3 Hz, HFF 35 Hz.[(:cite:pmid22701392>{{pmid>long:22701392}})]</figcaption>
