Relationship of EEG and tremorogram indicators

The existing facts and hypotheses regarding the localization of the "pacemaker" of tremor are rather controversial. Fundamentally, the development of tremor (TrG) is explained by the formation of an oscillator (a source of rhythmic activity) at any level of the central nervous system. The objective is to study the mutually oriented influences between the frequency and amplitude of the TRH rhythms and the electroencephalogram (EEG), reflecting the work of the generators (oscillators) of both oscillatory processes. It was revealed that more regression coefficients from the EEG indicators of both the right and left hemispheres were determined for the left hand TRG indicators. This may indicate that the generators that form the physiological tremor of the left and right hand are not identical, as well as that the physiological tremor of the left hand is to a greater extent controlled by the generators that form the EEG than the generators that form the tremor of the right hand. The largest number of regression coefficients of multiple regression analysis was determined by the rate of beta-1 rhythm of the left hand TrH from EEG indicators. It was shown that the generators forming the physiological tremor of the left and right hands are not identical. The physiological tremor of the left hand is to a greater extent under the control of the generators that form the EEG than the generators that form the tremor of the right hand. The generator of the alpha rhythm of the TrG of the left hand is an independent formation and is not similar to the generator of the alpha rhythm of the TrG of the right hand.
