| Abstract(in English) | In order to realize artificial vision by means of the cortical implant, it is critical to understand how the cortical responses evoked by electrical stimulation are transmitted to the higher-order visual areas. In the present study, we made analyses on the synaptic responses to electrical stimuli at the mouse primary visual cortex (V1) by the in-vivo imaging technique using a voltage-sensitive-dye, RH-1691. When a single pulse of the current stimulus was delivered through a glass microelectrode penetrating into the layer II/III of V1, a depolarizing response was induced around the stimulation site, and transmitted also to the higher-order visual areas. We found that such a signal transmissions can be modulated depending on the frequency of the repetitive pulse stimulation. |
