Abstract
Cortical oscillatory activity in the 40-Hz range has been observed in man during cognitive tasks and following sensory stimulation, as analyzed by electroencephalographic (EEG) and magnetoencephalographic (MEG) means (Galambos et al., 1981; Maekelae and Hari,1987; Sheer, 1989; Weinberg et al., 1988). Such oscillatory activity is not unique to man but has been seen in many mammalian forms during attentive states (Bouyer et al, 1987) and during physiological stimulation of the olfactory (Bressler and Freeman, 1980) or the visual systems (Eckhorn et al., 1988; Gray and Singer, 1989). However, these 40-Hz activity recording were restricted to localized brain areas and on occasion to small cell groups, to include a few cortical columns. Even in those studies where EEG and MEG recordings were attained, data analysis was restricted to a single time slice at the maximum positive or negative peak of an averaged evoked response. Nevertheless, these studies indicate that 40-Hz coherent neuronal activity large enough to be detected from the scalp is generated during cognitive tasks (cf. Sheer, 1989).
