In order to investigate the cytoarchitecture of cortex and the distribution of GABA- immunopositive cells in the cerebellum of Sanhuang chicken,the cerebellums of ten Sanhuang chicken were studied by Nissl staining and SABC techniques.The results showed that the cytoarchitecture of cerebellar cortex of Sanhuang chicken was similar to that of Pekin duck,silky fowl,pigeon and African Ostrich.GABA-immunopositive cells were located in the Purkinje cell layer of cerebellar cortex,and their immunopositive were especially strong. A large number of GABA-immunopositive cells were also distributed in the cerebellar nuclei,which taking on fusiform or irregular polygon and their cytoplasm were intensively stained.The results of the present study demonstrated that GABA-immunopositive cells were distributed in the cerebellar cortex,which had a vital influence on maintaining cerebellar complicated function.
