Output-based rather than input-based inhibition creates self-reinforcing asymmetric suppression.

Evidence

In other words, the asymmetry in the amount of contralateral inhibition of gain (or compression) was enhanced because it depended on the processors’ output rather on their input amplitudes. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1939

Categorization

• DEFINE: Clarifies the design principle: inhibition keyed to output (post-compression) rather than input yields an amplifying cascade absent from input-keyed circuits.
