In cats, electrocortical rhythms at about 10 Hz displaying common characteristics with the human alpha rhythm [1] were recorded from the part of the visual cortex that includes the anterior half of areas 17 (on the cortical convexity), of area 18 and of their common limit, representing the projection of the lower contralateral visual quadrant and that of the lower vertical meridian. It is shown here that activities highly correlated with these rhythms and at the same frequency, were recorded from the anterior half of the laminar dorsal lateral geniculate body (mediodorsal part of layer A), and also from a limited area medial to this nucleus. The cat thalamocortical alpha system thus appears to concern only the projection of the lower quadrants, probably excluding the area centralis itself.
在猫身上，从视觉皮层的一部分记录到了频率约为10Hz、与人类α节律具有共同特征的脑电节律[1]，该部分包括17区（在皮质凸面）的前半部分、18区及其共同边界，代表对侧下视觉象限和下垂直子午线的投射。本文表明，在层状背外侧膝状体的前半部分（A层的中间背侧部分）以及该核内侧的一个有限区域，记录到了与这些节律高度相关且频率相同的活动。因此，猫的丘脑皮质α系统似乎仅涉及下象限的投射，可能不包括中央区本身。
