MoP-25 DEVELOPMENT OF A LOCAL LIGHT STIMULATION DEVICE INTEGRATED WITH MICRO ELECTRODE ARRAY

Abstract

Optogenetics is a new technique for analyzing neural network in brain science. In optogenetics, neurons in a neural network is locally stimulated and controlled by visible lights. In this paper, we propose an integrated microchip having micro electrodes and micro lenses. The proposed microchip stimulates a brain slice sample with two focused lights which have different affection to the neuron, and measures the electrical reaction of the neural network.
