This study was designed to investigate the effects of Gastrodiae Elata Pharmacopuncure at GB20 on motor control and cognitive dysfunction recovery after mild traumatic brain injury in rats. Rats were divided into three groups; (1) no treatment after traumatic brain injury(experiment I), (2) Treatment with NPA after traumatic brain injury(experiment II), (3) Treatment with GEP after traumatic brain injury(experiment III). In our study, we carried out behavioral test(Rotarod, Morris water maze) and immunohistochemistry study of the change BDNF in the hippocampus(pre, $7^{th}$, $14^{th}$ day). In Rotarod test(motor control function) was significantly increased in the experimental group III as compared with experimental group I, II on $7^{th}$(p<0.01) and $14^{th}$ day(p<0.001). In Morris water maze test(cognitive function) was significantly decreased in the experimental group III as compared with experimental group I, II on $14^{th}$ day(p<0.001). In immunohistochemistric response of BDNF in the hippocampus, the experimental group III was more immune response than the other groups on $14^{th}$ day. These results imply that Gastrodiae Elata Pharmacopuncure at GB20 can play a role in facilitating recovery of motor control and cognitive function after mild traumatic brain injury in rats.
