Bioelectrical Activity of the Amygdala of Rats under Conditions of Chronic Alcoholism and Imbalance of Nitric Oxide

Abstract

Evaluation of biopotentials in the region of the amygdala of rats in the combined influence of alcohol and drugs, causing an imbalance of nitric oxide is described in this paper. Chronic alcoholism leads to structural morphological changes in the liver. A study of the amplitude of electrical activity showed that the electrical potential in the amygdala after 8 weeks chronic alcoholism was lower compared with normal rats. The frequency spectrum analysis showed decreased in the 2 times or more absolute spectral powers of all components. The relative spectral powers of its components: δ: θ: α: β was as a 2: 2: 2: 4. The use of sodium nitroprusside (donator of NO) together with the chronic consumption of ethanol reduces the effect of ethanol on low and high-frequence portion the performance of the bioelectrical activities spectrum in the amygdala. The use of non-selective blocker of NO-synthase – nitroarginine aggravated by the braking action of alcohol. The important role of nitric oxide in the development of adaptive-compensatory reactions of the damaged body is described. Our results may be useful to assess the contribution of NO in operation amygdala, conditions of chronic pathologies, and treatment of neuropsychiatric conditions, including diseases caused by alcohol abuse.
