The structure and ultrastructure of the sensomotor cortex in pubertal rats were studied 7, 14 and 21 days after acoustic stress. Focal peripheral chromatolysis and pigment accumulation by lysosomes were found in neurons after 14 and 21 days of exposure to noise. The number of lysosomes in which pigment was accumulated, and multivesicular bodies appeared, increased in the glial cells. The cavities of granular reticulum widened because of the accumulation by them of muddy secretion. These phenomena indicate the diffusive character of structural changes in the cortex of the large hemispheres under acoustic stress. It has been noted that young animals exposed to noise manifest changes characteristic of the process of aging.
对青春期大鼠在声音应激后7天、14天和21天的感觉运动皮层的结构和超微结构进行了研究。在暴露于噪声14天和21天后，神经元中发现了局灶性外周染色质溶解和溶酶体色素积累。胶质细胞中积累色素且出现多泡体的溶酶体数量增加。颗粒内质网的腔由于其积聚的浑浊分泌物而增宽。这些现象表明在声音应激下大脑半球皮层结构变化具有扩散性。已经注意到，暴露于噪声的幼小动物表现出衰老过程的特征性变化。
