Power spectral analysis of flash and click evoked responses.

Abstract Power spectral and digital filter analysis of flash and click evoked responses of ten, normal, right-handed subjects was carried out. Two major frequency groups were seen in the right and left auditory and occipital cortex responses of all subjects. Group I, 0–5 c/sec, was of long latency, occurred simultaneously and in a similar form in both the visual and auditory areas for both flash and click, and was always greater ( P P
