Jerome Pine, a neurophysicist at the California Institute of Technology in Pasadena, along with a team of electrical engineers and biologists, created a microscopic silicon landscape that confined individual neurons, while allowing them to establish connections: a set of 16 tiny wells, each about 1/40 of a millimeter in diameter, with short tunnels leading to the surface.
