| Research Abstract |
We have carried out optical imaging studies, behavioral studies, as well as electrophysiological studies to probe the function of auditory fields in guinea pigs. We found 1) focal activation of the primary auditory field at a single site can evoke an eyelid response conditioned with a pure tone, 2) there are spontaneous activity events in the primary field and some events exhibited a spatiotemporal pattern highly similar to the tone-evoked activity, and 3) frequency discrimination by the population activity of the primary fields outperforms behavioral frequency discrimination results. These results not only suggest a role of the primary auditory cortex in tone perception and frequency discrimination, but also have an impact on auditory prosthesis by cortical stimulation.
