We describe the features of the occurrence of the “monotony” state in practically healthy young adults. The materials of processing results of experimental data of test subjects (N = 13, aged 29 ± 4.3 years, men) are presented. Mathematical processing of the reaction time of the subjects during a long test on the perception of visual objects allowed us to identify two different response scenarios of the subjects, associated with more and less resistance to the occurrence of monotony in the process of uniform cognitive load. The differentiation of the subjects into two subgroups is confirmed by other objectively calculated characteristics (the number of erroneous decisions and average reaction time). The observed effects may be associated with the ability of the nervous system to adapt to prolonged stress.

The spatial changes in the EEG during odors impacts

K. Samatova, A. Titova, A. Varegnikov, A. Runnova

Proceedings Volume 11847, 118470O (2021) https://doi.org/10.1117/12.2590866

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.
