N-of-m stimulation strategies resist improvement from electrode deactivation.

Evidence

Some n-of-m (n channels with highest input amplitudes stimulated out of a possible m channels; e.g. ACE (8-of-22) or SPEAK) strategies may not benefit from deactivation of electrodes due to the simplification of the information delivery already inherent in the strategy. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2050

Categorization

• DEFINE: Defines n-of-m coding strategy: only the n highest-amplitude channels are stimulated each cycle.
