The claustrum is a telencephalic cell group (Fig. 1A, B) possessing widespread reciprocal connections with the neocortex. In this regard, it bears a unique and striking resemblance to the thalamus. We have now examined the anatomical ordering of pathways linking the claustrum with sensory areas of the cat neocortex and, in parallel electrophysiological experiments, have studied the functional organization of claustral sensory zones so identified. Our findings indicate that there are discrete visual and somatosensory subdivisions in the claustrum interconnected with the corresponding primary sensory areas of the neocortex and that the respective zones contain orderly retinotopic and somatotopic maps. A third claustral region receiving fibre projections from the auditory cortex in or near area Ep was found to contain neurones responsive to auditory stimulation. We conclude that loops connecting sensory areas of the neocortex with satellite zones in the claustrum contribute to the early processing of exteroceptive information by the forebrain.
屏状核是一个端脑细胞群（图1A、B），与新皮质有着广泛的相互连接。在这方面，它与丘脑有着独特而显著的相似之处。我们现在已经研究了连接屏状核与猫新皮质感觉区的通路的解剖学排序，并且在平行的电生理实验中，研究了如此确定的屏状核感觉区的功能组织。我们的研究结果表明，屏状核中存在离散的视觉和躯体感觉亚区，它们与新皮质相应的初级感觉区相互连接，并且各自的区域包含有序的视网膜拓扑图和躯体拓扑图。发现第三个屏状核区域接收来自Ep区或其附近听觉皮质的纤维投射，该区域含有对听觉刺激有反应的神经元。我们得出结论，连接新皮质感觉区与屏状核卫星区的环路有助于前脑对外感受信息的早期处理。
