The neuron-semiconductor interface (continued)

This press release from the Department of Membrane and Neurophysics at the Max Plank Institute for Biochemistry, Martinsreid, describes a neuron-semiconductor interface.

The work is part of the ongoing the NACHIP project, which I described recently, and is published in the Journal of Neurophysiology.

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).
