Scanning electron micrograph showing neurons from rat hippocampus cultured for 4d in serum-free medium on a silicon chip with a silica surface coated with poly-L-lysine. Scale bar, 10 μm. The linear array of open transistors is seen in the center, with the drains and the lanes of field oxide directed upward and with the common source at the bottom.
