Presented paper reviews recent literature data about the role of non-specific mechanisms of central nervous system adaptation and intrinsic properties of organism functional systems in the effects of rhythmical sensory influences. Among the reviewed factors which determine particular effectiveness of relatively weak, but rhythmically organized external… (More)
Biofeedback (BFB) training paradigm has outstanding place among various approaches to non-phrarmacological human functional state correction. Being an universal way for voluntary self-regulation of physiological functions, it is characterized by efficacy, accessibility and absence of side effects. However, the lack of fundamental knowledge about the BFB… (More)
The possible mechanisms which determine the temporal dynamics of discrete narrow-band spectral components of human EEG recorded by a single electrode in the state of rest were analyzed. The dynamics of short-segment spectra was observed by application of Fast Fourier Transform (FFT) to 5-s EEG epochs successively shifted by 0.32 s. For each subject the… (More)
Grown-up subjects revealed both unspecific and specific bimanual motor responses to photostimulation with growing and declining frequency. The former mode of stimulation proved more effective. A relation was found between the physiological responses of subjects and their subjective condition.
The photoinduced resonance EEG response in the occipital area (O1 and O2) of right-handed men during 12-s intermittent photic stimulation was studied as a function of flash frequency (6, 10, or 16 Hz) and intensity (5 levels from 0.05 to 0.7 J). The EEG power in the narrow band coinciding with stimulation frequency was FFT-extracted in 3-s intervals before,… (More)
During the past decade, spectral analysis has become indispensable instrument for different kinds of EEG processing. With the development of dedicated computer system, investigation of shifts in human EEG rhythm under various conditions has improved considerably. However, it is difficult to make general conclusions from this line of research, since a large… (More)
