| Outline of Final Research Achievements |
To reveal the mechanism for experience-dependent reorganization of cortical neural circuits, we used mutant mice which have impairment of hearing. Immunohisotochemical analysis for fos protein which is activity dependently expressed in neurons were performed. We found that fos-expressing neurons in auditory cortex of mutant mice were more frequent than that of naive mice. Furthermore, we found that acetylcholine and serotonin modulate the cortical activity by the facilitation or the depression during exploration and stationary state, respectively.
