Figure 1

Pathways for activation of medial (MOC) and lateral olivocochlear (LOC) efferent fibers to the right cochlea. Red and blue lines illustrate the pathways for activation of the contralateral and ipsilateral MOC reflexes, respectively. Green lines illustrate the pathways for activation of the LOC reflex. The thickness of each line roughly illustrates the density of innervation. Abbreviations: LSO, lateral superior olive; MNTB, medial nucleus of the trapezoid body; PVCN, postero-ventral cochlear nucleus; SOC, superior olivary complex; VNTB, ventral nucleus of the trapezoid body; CF, characteristic frequency.
