Research Abstract

In this study, I examined characters of cells expressing cadherin20 in the lateral striatal region and somatosensory cortex in adult rats using in situ hybridization and immunohistochemistry. These studies revealed that all cadherin20+ cells in the lateral striatum were both direct and indirect pathways medium spiny projection neurons. I also established the method to determine relationship between asymmetric expression of cadherin20 and handedness in rats. We could distinguish left or right-handedness of rats using this method.
