Morphometric Characteristics of the Structure of the Central Nucleus of the Amygdaloid Complex in Men and Women

Abstract

Objectives. To identify interhemisphere asymmetry in the structure of the central nucleus of the amygdaloid complex in men and women. Materials and methods. The morphometric characteristics of neuron structure in the central nucleus of the amygdaloid complex were determined on histological sections of the brain from six men and six women (24 hemispheres) aged 19–55 years with no history of mental or neurological disease while alive. Neuron profile field sizes were determined in the central nucleus of the amygdaloid complex in the left and right hemispheres of the brain. Results and discussion. Mean neuron size in women was somewhat larger in the left hemisphere than the right, while mean neuron size in men was greater on the right. Neither men nor women showed any statistically significant interhemisphere morphometric differences. Furthermore, neuron profile field size in the central nucleus of the amygdaloid complex in women was statistically significantly larger than in men in both hemispheres. An attempt was made to link these data with the characteristics of emotional perception in men and women.
