The morphology and topography of neurons whose axons form the thalamic nonspecific input to the primary somatosensory cortex were studied in the cat thalamus by the method of the retrograde transport of the horseradish peroxidase. The labelled cells were found in the dorsolateral part of the nucleus ventralis anterior, in the nucleus centralis lateralis, in the lateral part of the nucleus dorsalis medialis, in the dorsal part of the nucleus centrum medianum. A very small number of slightly stained cells were found in the nucleus paracentralis. The variety of the shape, size and intensity of labelling of the HRP-positive cells was observed in each thalamic structure. The results of the experiments indicate that not only the ventrobasal complex but also the nonspecific thalamic nuclei are projected to the primary somatosensory cortex. These data demonstrate the existence of multiple afferent thalamic inputs to the primary somatosensory cortex.
采用辣根过氧化物酶逆行运输法，在猫丘脑研究了轴突形成丘脑至初级体感皮层非特异性输入的神经元的形态和位置。在腹前核背外侧部、外侧中央核、背内侧核外侧部、中央中核背侧部发现了标记细胞。在中央旁核发现了极少数轻度染色的细胞。在每个丘脑结构中均观察到辣根过氧化物酶阳性细胞的形状、大小和标记强度的多样性。实验结果表明，不仅腹后基底复合体，而且丘脑非特异性核也投射到初级体感皮层。这些数据证明了初级体感皮层存在多种丘脑传入输入。
