Device for investigating functional connectivity of neural cells

摘要

An apparatus for analyzing nerve cell connectivity includes a light stimulator for applying a light stimulus to a stimulation target cell in a nerve tissue, an electrode for detecting a neural signal of the measurement target cell in the nerve tissue, And a computer for processing the neural signal information detected by the electrode, wherein a light gene inducing a change in cell membrane potential by the light stimulus is expressed in the cell to be stimulated, and the cell to be stimulated is stimulated by the light stimulus And the computer analyzes the relationship between the light stimulus state of the subject cell to be stimulated and the neural signal detected from the subject cell to derive a connection relationship between the neurons in the neural tissue.
