Abstract:
The fibre projections of the caudate nucleus to the cerebral cortex and the nonspecific thalamic nucleus in the rabbit were studied by tracing the degenerated axons and terminal fibres from electrolytic lesions in the head portion of the nucleus on sections prepared with Nauta and Glees methods.The results were as follows:The efferent fibres from the head portion of the caudate nucleus were projected to frontal (especially the praecentral areas) and limbic cortex, and terminated in all the layers of the cerebral cortex.The efferent fibres from the head portion of the caudate nucleus were projectet to the centromedian nucleus and parafascicular nucleus of the nonspecific thalamic nuclei.The above observations suggest that the projection of the efferent fibres from the caudate nucleus to the cerebral cortex and nonspecific thalamic nuclei may be a parf of the nonspecific conducting pathway; and the caudate nucleus is not only a part do the extrapyramidal system but a structure of the nonspecific conducting system which may serve as the morphological basis for the role played by the caudate nucleus in the acupunctural analgesia.
