| Research Abstract |
We have researched the mouse auditory cortex using transcranial flavoprotein autofluorescence imaging. We achieved three results as following. The first is the plasticity of right auditory cortex after sound discrimination learning. The responses to rewarded sound was similar to those of naive mouse, however the responses to unrewarded sounds were significantly depressed. The second is the detection of FM sounds selective areas in the mouse auditory cortex. The third is the visualization of ON and OFF responses after habituation of sustained responses.
