Development of Local Light Stimulation and Multi-point Measurement Device for Neural Network Analysis

Abstract

In brain science and psychology, one of the most important purposes of recent studies about neural network, biological circuit in brain, is to establish a method of treatment for the central nervous system disease, such as Alzheimer. Neurons in a neural network is stimulated and controlled by visible lights by Optogenetics methods. In this paper, we propose a microchip integrated micro electrodes, micro lenses, and pinholes. The proposed microchip is capable of stimulating a neural network with two focused lights which have different affection to the neuron, and measuring the electrical reaction of the neural network.
