[The mean level of EEG wave asymmetry as a possible correlate of the property of lability of the cerebral hemispheres].

The human nervous system's lability was studied with the aid of critic fusion frequency (CFF). The CFF was compared with the mean level of asymmetry of the EEG waves' fronts (MLA). The CFF was shown to be a relatively stable individual parameter whose value depended on the value of difference between occipital and frontal areas' MLA and those in the lower frontal areas.
