对地方性克汀病人大脑的听觉传导路进行了病理检查,对上橄榄核、内侧膝状体及颞横回中神经元胞体进行了体视学的测量。发现部分神经元变性坏死,并可见卫星现象。神经元胞体的体积密度和数密度均比正常人明显减少。证实地克病人听觉传导路存在病变。 Pathology was performed on the auditory conduction pathway in the brain of endemic cretinism, and stereological measurements of neuronal soma in the superior olivary nucleus, medial geniculate body and temporal transverse gyrus were performed. Found that some neurons degeneration and necrosis, and visible satellite phenomenon. Neuronal somatic bulk density and number density were significantly reduced than normal. Confirmed that there are lesions in the auditory pathway of Dick patients.
