[The effect of unconscious interoceptive afferentation on the spatial organization of the electrical activity in the human cerebral cortex]

Sviderskaia NE, Kovalev AA.

The model of human perception and cortical regulation of unconscious interoceptive signals from the internal organs (heart, lungs, liver, intestines) was created by acupuncture of the corresponding channels. The features of the spatial organization of cortical electrical activity were analysed. A positive effect (for example, a decline of initially 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 hemisphere 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 influence) correlated with less expressed (or of another character) changes in the spatial organization of electrical activity. The conclusion is drawn that reorganization of cortical activity is necessary for perception and regulation of unconscious interoceptive information. Functional significance of this reorganization consists in the restriction of processing of exteroceptive information.
