Abstract

In the area 17 of the cerebral cortex of guinea pigs cells with small and medial receptive fields (RF) are concentrated at the sites of separate groupings of neurons excited by flashes of diffusion light. There are also cells with large RF here. At such sites of the cortex when specific afferents are electrically stimulated many cells exhibit monosynaptic activation irrespective of their RF size. The main part of the neurons with large RF is situated in the areas of the cortex between the excited grouping and monosynaptical excitation is not inherent in such neurons. Most cells of these areas are not excited by specific afferents.

摘要

在豚鼠大脑皮层17区,具有小的和中等大小感受野(RF)的细胞集中在由漫射光闪光激发的神经元单独分组的部位。这里也有具有大感受野的细胞。在皮层的这些部位,当对特定传入神经进行电刺激时,许多细胞无论其感受野大小如何都会表现出单突触激活。具有大感受野的神经元的主要部分位于兴奋分组之间的皮层区域,并且这种神经元没有单突触兴奋的特性。这些区域的大多数细胞不会被特定传入神经所兴奋。
