The aim of the study was to analyze the structural and quantitative characteristics of the Amygdala and the primary somatosensory cortex alcohol-preferring and non- alcohol-preferring rats on cytoarchitectonic slices prepared by the method of Nissl. To measure the area of the study structures of Amygdala’s posterior division and primary somatosensory cortex used the frontal slices and the program JmageJ 1.38 (USA). Calculated the absolute and specific area. The specific area of Amygdala was determined in relation to the area of the appropriate hemisphere, specific areas of cortico-medial and basolateral groups in relation to the area of Amygdala. Calculated in the somatosensory cortex specific area of the fifth and sixth layers with respect to the total area of oral surface jaw region in the right hemisphere. The analysis revealed a significantly lower specific area of the primary somatosensory cortex and basolateral group of Amygdala in the right hemisphere in alcohol-preferring rats compared with non-alcohol-preferring rats. The specific area of Amygdala in the right and left hemispheres were not significantly different in alcohol-preferring rats, reflecting the absence of its asymmetry.
