  • Title: [The mapping of brain biopotentials in patients with the depressive syndrome].
    Author: Strelets VB, Avin AI, Zverev SN.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1990; 40(5):903-7. PubMed ID: 1964335.
    Abstract:
    By means of mapping method a study of spatial distribution of biopotentials was conducted (by alpha-rhythm power and by asymmetry of its energy). It is shown that in patients with depressive syndrome within maniac-depressive psychosis and schizophrenia main neurophysiological properties are paradoxical alpha-rhythm reaction in the frontal cortical regions in response to eyes opening, hyperactivation of the posterior areas of the left hemisphere and also dissociation between activation level of the anterior and posterior regions of the hemisphere, creating the picture of "transversal functional block". After the séance of electrostimulation the "block" disappeared both by alpha-rhythm power parameter and by the parameter of its energy asymmetry; and the activation of the left hemisphere sharply decreased being accompanied by improvement of clinic state of patients.
