Schematic representation of anatomical structures. Light purple area represents lesions determined using 7T MRI shown in Figure 2. (a) Midbrain slice showing CIC lesion and (b) midbrain and upper pontine slices showing pre-crossing left trochlear nerve involvement.. BIC: brachium of the inferior colliculus; CIC: central nucleus of the inferior colliculus; CoIC: cortex of the inferior colliculus; CTT: central tegmental tract; LL: lateral lemniscus; ML: medial lemniscus; MLF: medial longitudinal fasciculus; PAG: periaqueductal gray; RaN: raphe nucleus; STT: spino-thalamic tract; TrN: trochlear nucleus; XSCP: decussation of the superior cerebellar peduncle.. The anatomical details were drawn based on the study by Paxinos and Huang.
