title: [The electrophysiological characteristics of the compensatory and restorative processes in the central nervous system of neurosurgical patients in relation to the lateralization of the injury].
abstract: The authors studied the functional condition of the brain during the restorative period after operative damage to one of the hemispheres. In the early stages of the restorative period in neurosurgical patients with a slow rhythm afferent stimuli (rhythmic light stimulation) induced the appearance of a marked alpha-rhythm, which is evidence of restoration of the functional condition of the cortical and subcortical structures taking part in the generation of this rhythm. Such dynamic changes in the condition of the structures may be considered as a manifestation of their activation and evaluated as a favourable prognostic sign. Data were obtained which characterized the features of the restorative-compensatory process depending on which hemisphere, right or left, the damage was inflicted. According to the indices of the various rates of EEG, high-frequency waves of beta-range prevailed in the intact left hemisphere on the 12th-25th day; this phenomenon was not recorded in an intact right hemisphere in damage to the left hemisphere.
