The microscopic electrical interfacing of semiconductor devices and living neuronal systems is considered. On the biological side, recombinant ion channels, identified nerve cells from snails and brain tissue from rats are used.

The mechanism of interfacing is studied with individual capacitors and field-effect transistors made with simple silicon chips. The approach is extended to chips with thousands of contact sites as fabricated by industrial silicon technology. The goal of the methodical development is the implementation of experimental neurocomputing.
