The spatial changes in the EEG during odors impacts

摘要

Spatial changes in surface EEG activity under the influence of odor were studied. The group of subjects included young neurologically healthy men (N = 3) and men with chronic headache (N = 3). An experimental technique was proposed that made it possible to assess the average spatial activity of the brain of the subjects, which arises during the perception of aroma. On the basis of a comprehensive analysis of oscillatory EEG - activity, statistically significant changes were found for the frontal and parietal projections of the cerebral cortex that occur when exposed to odor. We described changes of the same type within the group in the ratio of the powers of the observed vibrational activity in standard neurophysiological ranges.
