Abstract:
Neuropeptide Y(NPY) was first isolated from porcine brain. This discovery has led some workers to study the distribution of this peptide in the central nervous system of various mammals. In this study examined the distribution pattern of NPY-immunoreactive (NPY-IR) neurons in the Striped Field Mouse (Apodemus agrarius coreae) cerebral cortex and striatum, using immunohistochemical method. The results obtained in this study were summarized as followings. 1. NPY-IR neurons distributed in all layer of cerebral cortex. The number of neurons were higher in layer V and VI than in layer I and IV. 2. The shape of neurons was predominantly round or oval in layer I and II, and triangular in layer V and VI. And the processes were parallel to pia mater in layer I and II and were vertical in layer III. 3. The highest number of NPY-IR neurons were found in the perirhinal cortex but a few distinct population were found in the retrosplenial cortex. 4. In stiatum NPY-IR neurons were observed only in caudate-putamen nucleus. 5. The Immunoreactive neurons in caudate-putamen varied in their shape, but most of them were triangular or multiform neurons had omnidirectional processes.
