Once a certain voltage threshold is achieved the material oxidizes, releasing an electric charge.

Motorneurons of different sizes have similar voltage thresholds.

The oscilloscope triggers when the signal crosses one of two voltage thresholds, but not both.

Compression of the dorsal root ganglion by a mechanical stimulus lowers the voltage threshold needed to evoke a response and causes action potentials to be fired.

Also, every electrolytic reaction has a fairly sharp voltage threshold (maybe 0.02v, but definitely less than 0.1v wide).

They discovered the Buneman-Hartree criteron for the voltage threshold of magnetron operation.

All else being equal, millionfold faster operation requires millionfold greater currents to reach a given voltage threshold.

The binding of ikitoxin lowers the voltage threshold of sodium channels and produce a reduction in the current amplitude.

Above the voltage threshold, the third harmonic appears, and the amplitude of the distortions increases as the square of the voltage.

If the conductance fluctuates below the voltage threshold for Na1.4, then the sodium channels will eventually be able to close, and be depolarised again.
