title: [Human attention as a specific linkage of EEG rhythms with the wave modulators of the cardiac rhythm].
abstract: Two types of attention (active and passive) were described as specific correlations between central and peripheral oscillatory processes. The active attention was characterized by an enhance of the activity of the high-frequency respiratory heart rate modulator positively correlated with an increase in the EEG gamma-rhythm power. At the same time, the activity of the low-frequency heart-rate modulator was positively correlated with the depression of the low-frequency EEG and with phasic gamma-rhythm reactions (300 ms after stimulus presentation). During the passive attention, the power of the metabolic hear rate modulator increased, its positive correlation with the spectral power of the low-frequency EEG rhythms was observed. The sensory component of the gamma-rhythm was shown to increase with attention attraction.
