Webb7 apr. 2024 · During learning, distinctive faces increased early visually-evoked (N170, P200, N250) potentials relative to non-distinctive faces, and face distinctiveness modulated voice-elicited slow EEG activity at the occipito–temporal and fronto-central electrodes. Webb7 nov. 2006 · EEG activity for most of normal sleep is characterized by slow‐wave activity (SWA) that corresponds, at a cellular level, to slow oscillations of membrane potentials of cortical neurons (41, 42). The amount of EEG SWA is homeostatically regulated, showing an increment during wakefulness and returning to baseline during sleep .

WebbThe 6-Hz spike-and-wave (phantom spike-and-wave) is a benign EEG variant initially described in 1950 (Walter, 1950 ). “Phantom” is derived from the low-amplitude spike within a burst of spike-and-slow wave activity ( Fig. 9.9 ). The amplitudes of the discharge are low with the spike component usually < 40 μV, and the aftergoing slow wave ... Webb8 sep. 2009 · Increased EEG Slow Oscillation Activity. The ability of tSOS to enhance slow oscillatory activity even during wakefulness in the prefrontal cortex, which is the preferential source of the endogenous sleep slow oscillation ( 26, 27 ), may indicate increased frontocortical susceptibility to electric field fluctuations in this frequency.
