Are fast ( 40-150Hz ) oscillations associated with positive slow waves in the ictal EEGs of epileptic spasms in West syndrome? Context: To elucidate the generative mechanisms of epileptic spasms (ESs) in West syndrome, we investigated the temporal relationship between scalp fast (40-150Hz) oscillations (FOs) and slow waves in the ictal electroencephalograms (EEGs) of ESs. In 11 infants with WS, ictal FOs were detected in a bipolar montage based on spectral and waveform criteria. Their temporal distribution was analyzed in terms of the positive peaks (trough point, T We identified a total of 1014 FOs (946 gamma and 68 ripple oscillations), which clustered closely at T

The temporal association of FO clustering and positive slow waves in the ictal EEGs of ES indicated that active neuronal firing related to FOs underlies the generation of ESs and their ictal slow waves. Final Decision: yes
