The above image shows a rat neuron growing on an electrolyte-oxide-silicon transistor (a) and a schematic cross-section of a neuron on a transistor (b). (Max Plank Institute for Biochemistry.)
The image above shows an electron micrograph of a two-way contact with a polyimide picket fence (a, scale bar= 20 micrometres; St, stimulator wings, S, source, D, drain, G, gate), an electron micrograph of a fixed neuron from the A cluster of the pedal ganglia of the Greek pond snail Lymnaea stagnalis in a picket fence (b, scale bar= 20 micrometres); and a micrograph of cultured nerve cell bodies in picket fences on a circle of two-way contacts connected by neurites (c, scale bar= 100 micrometres).
