ABSTRACT

The noninvasive examination of Spatial-Frequency (SF) patterns embedded within the continuous EEG is an area of great interest in medicine and psychophysiology [l>2]. Spectral methods of SF analysis examine the brain’s use of oscillatory communication as a means of executive control and are a likely candidate as an index of cognitive functioning in humans [3 4]. The topic of this paper examines the spatial relationship of the banded power in brain waves recorded at the scalp as a predictor of arousal and performance changes during complex higher order cognitive processing in man.
