| Research Abstract |
Previous studies on the neural functions of auditory cortex were commonly conducted on anesthetized or strained animals. In the present study, we for the first time used free moving cats. Cats were trained to perform a Go/NoGo behaving task to discriminate continuous and interrupted sounds. We then implanted multiple-channel electrodes into the primary auditory cortex and high order auditory cortices, and recorded the neural activities during the cats performed the task. By analyzing the relation between neural activities and behavioral responses, we revealed the neural response patterns correlating to the discrimination between continuous and interrupted sounds. Furthermore, we recorded the neural activities in various brain areas as the cats were actively discriminating the sounds and passively listening to the same sounds. By comparing the neural responses under the two conditions, we revealed the effects of auditory attention on various brain areas.
