Triphasic morphology
WebAug 26, 2014 · We defined triphasic sharp waves and spikes (FTSW) as IEDs with prominent, sinusoidal (dome-shaped) after-coming slow waves (ASW) with negative polarity, giving rise to a triphasic morphology. Characteristically, there was a prominent positive trough between the fast (negative) component and ASW. The amplitude of ASW ranged from 100 to 300 … WebApr 3, 2024 · The original Triphasic schedule consists of 3 single-cycle equidistant sleep blocks; one sleep cycle every 8 hours.
