[Comparison of dynamic cortical electroencephalotopograms of the human left and right cerebral hemispheres in quiet...

The differences of spatial-temporal organization of potentials in the left and right hemispheres were studied in healthy subjects at calm alertness by means of comparison of successive electroencephalotopograms (EETGs). In all subjects episodes were found of discordance resemblance coefficient of successive EETGs of the left and right hemispheres--one of the main characteristics of potentials spatial-temporal organization. The episodes of such discordance took as a whole 5--57% of observation time; the duration of each episode could vary from the sampling interval (1/128 s) to the period of resemblance coefficient oscillations.
