Abstract
An identified nerve cell of the leech is attached to a planar silicon
microstructure of p-doped silicon covered by a thin layer of
insulating silicon oxide. A voltage-step, applied between silicon
and electrolyte, induces a capacitive transient in the cell which
elicits an action potential. The capacitive extracellular stimulation
is described by an equivalent electrical four-pole.
