Inferior colliculus neurons show only three types of modulation tuning that can be modeled

Evidence

Phenomenological models were used to simulate the three types of rate modulation transfer functions (MTFs) that comprise the bulk of IC neurons (Kim et al. 2015a ): band-enhanced, band-suppressed, and hybrid (Fig. 1 ). The first two MTF types have discharge rates to AM stimuli that are enhanced or suppressed relative to responses to unmodulated stimuli (Kim et al. 2015a , 2015b ). Hybrid MTFs have discharge rates that are enhanced at some modulation frequencies and suppressed at others (Krishna and Semple 2000 ; Kim et al. 2015a ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5480
