Standardized neural chips often use a multi-chamber structure. Multiple culture chambers are connected by narrow channels, and the specific growth of axons can be achieved by controlling the height and length of the channels. When the height of the microchannel is less than 5 μm, only neurites can enter the tunnel, and when the length of the microchannel exceeds 400 μm, only axons can extend into another chamber.
