Silicon-neuron junction: capacitive stimulation of an individual neuron on a silicon chip.
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.

Neuron-silicon junctions were spontaneously formed using nerve cells of a mammalian brain, permitting direct stimulation of nerve cells.
“Neuron-silicon junctions were spontaneously formed using the nerve cells of a mammalian brain, which permitted direct stimulation of nerve cells (Fromherz and Stett, 1995; Offenhausser, 1996; Vassanelli and Fromherz, 1997; Schätzthauer and Fromherz, 1998).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
