UNCONSCIOUS INTEROCEPTIVE REGULATION OF T HE SPATIAL-ORGANIZATION OF CORTICAL ELECTRICAL-ACTIVITY IN HUMANS

The model of human perception and cortical regulation of unconscious i nteroceptive signals from the internal organs (heart, lungs, liver, in testines) created by acupuncture of the corresponding channels. The fe atures of the spatial organization of cortical electrical activity wer e analysed. A positive effect (for example, a decline of initialy high heart rate) was accompanied by a fall in the general level of spatial synchronization, a decrease in the linear and non-linear correlations between potentials led from the anterior areas of the right hemispher e and the left posterior areas, and a growth of coherence in the range of 21.5-23 Hz. Absence of the acupuncture effect (or its negative inf luence) correlated with less expressed (or of another character) chang es in the spatial organization of electrical activity. The conclusion is drawn that reorganization of cortical activity is necessary for per ception and regulation of unconscious interoceptive information. Funct ional significance of this reorganization consists in the restriction of processing of exteroceptive information.
