Abstract

The alpha wave (8~13 Hz) phase resetting from pre-stimulus to post-stimulus is investigated for eight healthy subjects in a visual and auditory synchronously oddball stimuli experiment. Six parameters are considered: pre-stimulus amplitude and phase angle, post-stimulus amplitude and latency of first positive and negative peak. The results show that the amplitude relationship between pre- and two post-stimulus can be described by a cubic polynomial model; and by using the method of outlying cases test partial phase resetting from pre- to post-stimuli in the band of alpha wave was confirmed in visual and auditory synchronously oddball stimuli experiment
