Neuron-electrode interfaces are developed on thin silk films as brain implants. Silk films can use surface topography to induce astrocyte alignment, and microfluidic systems to generate patterned axon tracts. With built-in wire connections in the film, cortical neurons produce robust calcium responses upon electrical stimulation. These brain-compatible implants could potentially provide sustained functional neuron-electrode interfaces for the brain.
