Caption: A thin tissue slice of a rat hippocampus region (top) is cultivated on a semiconductor chip with 16.384 sensory transistors per square millimetre (center, dark coloured square). Following excitation the chip maps the electrical activity of the neurons (bottom), caused by activity of synapses (red: positive, blue: negative).
