本文应用HRP逆行追踪技术对猫丘脑腹后内侧核内投射神经元向头面部躯体感觉皮质区的定位投射进行了研究。结果证明,猫丘脑腹后内侧核大细胞部的内侧部投射至冠状回下部;腹后内侧核大细胞部的中部投射至冠状回上部;腹后内侧核大细胞部的外侧部投射至上斯氏回前下部。本文所见标记细胞均出现于HRP注射部位的同侧,为中型圆及椭圆形细胞。
In this paper, HRP retrograde tracing technique was used to study the projection and projection of projecting neurons into the somatosensory cortical area of the head and facial region in the posterior medial nucleus of the thalamic thalamus. The results show that the medial portion of the ventral medial nucleus of the thalamus is projected to the lower part of the coronoid gyrus; the middle part of the medial ventral large nucleus cell is projected to the upper part of the coronoid gyrus; the lateral part of the medial ventral nucleus granulosa is projected onto the upper part of the corpus striatum Back to the front. The labeled cells seen in this paper all appear on the same side of the injection site of HRP, which are medium-sized round and oval cells.
