| Abstract(in English) | In guinea pig's primary auditory cortex, tone-evoked neuronal activities are known to propagate along isofrequency strips. The reason for such anisotropic propagation of activity has not been made clear. Here we address this issue by examining the spatiotemporal pattern of cortical activity evoked by focal electrical stimulation. Cortical activity was recorded with an optical recording method, using a voltage-sensitive dye, RH795. We found that activity evoked by a single electrical pulse applied focally within the primary auditory cortex, propagated in a spatial pattern similar to that of tone-evoked activity. 0ur results suggest the possibility that primary auditory cortex supports activity propagation along the isofrequency direction, but limits activity propagation in the orthogonal direction. |
