Pathological and adaptive-compensatory alterations of rat cerebral cortical beta-adrenergic receptors have been demonstrated using the model of experimental neurosis developing as a result of chronic emotional painful stress. After the first week of stress increases of both Kd and Bmax occur; both indexes reach control levels after 3 weeks of neurotization. The changes of cortical beta-adrenoreceptors accompany transient fall of cholesterol-to-phospholipid ratio and decrease of free radical lipid oxidation in brain cortex. The normalization of all cerebral parameters after 3 weeks of stress coincides with the activation of lipid peroxidation in blood serum.
