METHOD FOR EVALUATING AND CORRECTING FUNCTIONAL STATE OF HUMAN CEREBRAL CORTEX Russian patent published in 1999 - IPC

FIELD: medicine. SUBSTANCE: method involves exposing visual analyzer of a testee to colored pulsating radiation like green and red light and at the same time showing verbally inexpressible, emotionally colored, indifferent or character information material corresponding to eye domination type under dominant-to-subdominant interhemisphere interaction. The action is carried out in dichoptic mode colored pulse action intensity being stepwise changeable and light pulse succession frequency being smoothly varied at every step the intensity changes. Critical frequencies of brain stimulation are measured under each color and subjectively perceptible information material is concurrently determined to find out the degree of prevalence of right and left eye perception and color asymmetry index dynamical change. Functional brain state estimations are calculated from measured characteristics of color vision and correction action parameters for increasing functional cerebral reserve are determined. Correction is carried out by sending color pulses of given intensity and frequency into known zones of visual analyzer. EFFECT: high accuracy in differentiating functional brain states; enhanced effectiveness of correction method. 15 cl, 23 dwg, 1 tbl
