Reactions of neurons in different areas have been investigated in the hedgehog cortex by means of the microelectrode technique. A wide dispersion of afferent inputs was shown over the whole neocortex, alongside with the existence of definite projection foci of appropriate modalities. In the specific projection zones the conditioning heterosensory stimulation did not influence the onset of the response of the testing specific stimulus. Blocking of responses was observed in the so-called "associative" area, irrespectively of the mode of the conditioning and testing stimulation. It is suggested that the onset of responses by the specific projection zones to other stimuli depends on the specific impulsation irradiation to the specific projection pathways. Reciprocal heterosensory blocking in the "associative" zone may indicate the existence of an integrative formation in the hedgehog thalamus, possessing its own projection to the neocortex.
借助微电极技术，对刺猬皮层不同区域的神经元反应进行了研究。结果显示，在整个新皮层中，传入输入广泛分散，同时存在相应模式的明确投射焦点。在特定投射区域，条件性异感觉刺激并不影响测试特定刺激反应的起始。在所谓的“联合”区域观察到反应阻断，这与条件性和测试性刺激的模式无关。研究表明，特定投射区域对其他刺激的反应起始取决于向特定投射通路的特定冲动辐射。“联合”区域中的相互异感觉阻断可能表明刺猬丘脑存在一种整合结构，该结构向新皮层有自身的投射。
