家兔大脑皮质内树突与血管的联系

THE DENDRITE-VASAL RELATIONS IN THE CEREBRAL CORTEX OF THE RABBIT

引言关于神经与血管之间的联系问题,至今研究的还不够,特别是大脑内的神经-血管联系的研究更少。过去,对神经元的突触问题做过不少工作。Cajal(1934)将中枢神经系统内的突触分成轴体突触和轴树突触。张香桐(1957)^([1])将这两种突触分别称为胞体上的突触或包围性突触和树突上的突触或依傍性突触。

The present work deals with the dendrite-vasal relations in the cerebral cortex of the adult rabbits.The brain pieces taken from the visual,auditory,somatic sensory and motor areas were prepared by the silver impregnation methods of Golgi and Golgi-Deineka.In the silver impregnated specimens,the findings showed that there were numerous dendrite processes of the neurons are topographically closely connected with the blood vessels in the cerebral cortex.The axo-and dendrite-vasal synaptic relations were found in these areas.The types of the dendrite-vasal relations in the cerebral cortex were very complex.The gemmules of the dendrites contacted with both capillaries and large vessels.
