Background:
The ability to control motor actions and flexibly interact with the environment is considered one of the main components of the human brain executive functions. The spontaneous electroencephalogram (EEG) is among the physiological techniques making it possible to formulate a direct estimation of specific features of the activity of the...

... increased coherence of the EEG α1-, α2-and β-oscillations was recorded in men with a high individu- al α-frequency in the frontal, temporal and central parts of their cortex (p ≤ 0.05). Such a regularity has the great- est significance in α2-subdiapason (with p ≤ 0.05 and p ≤ 0.01; Fig. ...
Context 2
... increased coherence coefficients in the cortex has relatively greater prevalence and importance in the cortex especially at a frequency of α2-, α3-, β-and γ-activity (with p ≤ 0.05 and p ≤ 0.01) in men with a low individual α-frequency than in men with a high IαF (Fig. 3). At the same time, the reduction in coherence was primarily found out in the anterior cortical areas in the strip of the EEG α1-, α3-and γ-oscillations (p ≤ ...

... People with a low α-frequency were characterized by less specific and differentiated cortical activation processes [20,21,23]. The functional differences previously identified in men during their performance of MMs by the subdominant hand [22] may reflect a generally relatively lower tone of cortical activation in men with a low IαF that can be specifically compensated for by increased "intensity" and an observed redundancy of brain processes. Despite the significant achievements made in this field, the literature remains sparse regarding the features of brain processes in women during MMs executed with the help of the subdominant hand. ...
... The nature of responses in the survey and execution of the motor and psychoacoustic tests were determined. The individual profiles of the manual motor asymmetry as well as auditory asymmetry were counted for each woman (K skew) (Formula 1) [20][21][22][23][24]. Further studies involved dextral examinees whose coefficients of manual and auditory asymmetries were positive and were above 50% [21,22]. ...
