| Outline of Final Research Achievements |
We investigated the cognitive function and neuronal morphological characteristics of major histocompatibility complex (MHC) class I deficit mice as an animal model of attention deficit/ hyperactive disorder. MHC class I deficit mice showed motor impulsivity and inattention. However there are no differences between wild-type mice and MHC class I deficit mice in acquisition of spatial learning and reversal learning tasks, and cognitive impulsivity. Neuronal characteristics were analyzed using Golgi-Cox staining. In the nucleus accumbens, there are no differences between wild-type mice and MHC class I deficit mice in dendrite length and number of branches. In the striatum, the percentage of immature spine was greater in MHC class I deficit mice than wild-type mice. In the cingulate cortex area1, MHC class I deficit mice had longer dendrite, and also larger number of branches compared to wild-type mice.
