Sensitivity to temporal modulation rate and spectral bandwidth in the human auditory system: fMRI evidence.

abstract：:Tinnitus and hyperacusis are common, burdensome sources of morbidity with a high rate of co-occurrence. Knudson et al. (J Neurophysiol 112: 3197-3208, 2014) demonstrated that efferent suppression of cochlear activity by the medial olivocochlear system is enhanced in individuals with tinnitus and/or hyperacusis. Their ...
