Abstract :
Properties of the neural responses to electrical stimulus pulses delivered at various inter-pulse intervals were examined in the visual cortices of mice in vivo, with utilizing the voltage-sensitive dye imaging technique. Our experimental results provided the relationships between the inter-pulse intervals and the stimulus-evoked transient depolarizations, which may offer insight into the design of effective and efficient stimulation for cortical visual prostheses.
