Lower layers of the isolated slab in the auditory cortex were cut, one, two or three cortical layers under the pial surface remaining intact. Impulse reactions of neurons to the intracortical stimulation applied on the other side of this additional cut were investigated in acute experiments on unanaesthetized immobilized cats. It was shown that stimulation of layer IV generated a flow of excitation ascending to the upper cortical layers and activating mono- and polysynaptically neurons of all layers through the vertical bundles of apical dendrites of pyramidal cells. Suggestion is made about an important role a large bundle of axons of layer III plays in the horizontal spread of excitation in the cerebral cortex.
切除听觉皮层中分离板的下层，软膜表面下的一、二或三层皮层保持完整。在未麻醉的固定猫的急性实验中，研究了神经元对在这个额外切口另一侧施加的皮层内刺激的冲动反应。结果表明，对IV层的刺激产生了兴奋流，该兴奋流向上传到皮层上层，并通过锥体细胞顶端树突的垂直束单突触和多突触地激活所有层的神经元。有人提出，III层的一大束轴突在大脑皮层兴奋的水平传播中起重要作用。
