The projection areas of mitral cell axons in the lateral (LOT) and medial (MOT) olfactory tracts and the pathways of two groups of centrifugal fibers (with fast and slow conduction velocities) to the olfactory bulb were studied in the carp using the field potential method. Mitral cell axons of the LOT and those of the MOT projected to the overlapping areas in the bilateral telencephalon and preoptic area (POA), the contralateral MOT, and the nucleus posterior tuberis (NPT) in the diencephalon. However, the precommissural, ventromedial part of the ipsilateral telencephalon received the projection only from mitral cell axons of the MOT, not from those of the LOT. No projection was detected in the contralateral LOT and the contralateral olfactory bulb. The distribution of the fast and slow centrifugal fibers and/or their cells of origin were similar to each other. They were distributed bilaterally in the telencephalon and POA, in the NPT, and contralateral LOT and MOT. These areas overlapped with the projection areas of the mitral cell axons considerably. The results support and extend those obtained from anatomical studies.
采用场电位法，在鲤鱼中研究了嗅叶内侧（MOT）和外侧（LOT）嗅束中二尖瓣细胞轴突的投射区域，以及两组离心纤维（传导速度分别为快和慢）至嗅球的通路。LOT和MOT的二尖瓣细胞轴突投射至双侧端脑和视前区（POA）的重叠区域、对侧MOT以及间脑的后结节核（NPT）。然而，同侧端脑的连合前腹内侧部分仅接受来自MOT二尖瓣细胞轴突的投射，而不接受LOT的投射。在对侧LOT和对侧嗅球中未检测到投射。快和慢离心纤维及其起源细胞的分布彼此相似。它们双侧分布于端脑和POA、NPT以及对侧LOT和MOT。这些区域与二尖瓣细胞轴突的投射区域有相当大的重叠。这些结果支持并扩展了解剖学研究所得出的结论。
