Neuronally isolated auditory cortical slabs (zone Al) of cat were studied using histochemical AChE reaction 3 days and 1, 2, 3 weeks after isolation. Following structures were observed: cholinergic long-axon associative neurons responding to the cortex isolation by retrograde degeneration and AChE hyperreaction (Cajal-Retzius cells of layer I and neurons of layer VI whose axons travel to the subcortical layer of the associative fibres); cholinergic short-axon associative cells of layers II-VI, which retain normal structure and moderate AChE activity after isolation; their axon collaterals terminate on neighbouring neurons; short-axon neurons are more numerous in deeper layers of the cortex; on the whole they predominate over the long-axon associative neurons; cholinoceptive cells (pyramidal and stellate) were found with cholinergic terminals on the soma and proximal parts of the dendrites; these terminals were formed by associative cell axons. Cholinoceptive neurons occurred more frequently in deeper layers of the cortex.
采用组织化学乙酰胆碱酯酶反应，对猫的神经元分离听觉皮质板（A1区）在分离后3天以及1、2、3周进行了研究。观察到以下结构：胆碱能长轴突联合神经元，通过逆行性变性和乙酰胆碱酯酶高反应（I层的卡哈尔-雷茨厄细胞和VI层的神经元，其轴突伸向联合纤维的皮质下层）对皮质分离作出反应；II - VI层的胆碱能短轴突联合细胞，分离后保持正常结构且乙酰胆碱酯酶活性适中；它们的轴突侧支终止于相邻神经元；短轴突神经元在皮质深层较多；总体而言，它们比长轴突联合神经元占优势；发现了胆碱感受细胞（锥体细胞和星形细胞），其胞体和树突近端有胆碱能终末；这些终末由联合细胞轴突形成。胆碱感受神经元在皮质深层出现得更频繁。
