Comparison of NADPHd cell density of the superior olivary complex between a 15- and a 35-year-old animal. Comparison of micrographs from a 15-year-old medial nucleus of the trapezoid body (MNTB; A) and a 35-year-old MNTB (B) reveals no apparent age-related changes in density. However, when comparing a 15-year-old medial superior olive (MSO; C) with a 35-year-old MSO (D), age-related density changes become apparent. Similar to the MNTB, the lateral superior olive (LSO) showed no clear age-related changes between the 15-year-old (E) and the 35-year-old (F) animal. Dorsal is upward and medial toward the left. Scale bar = 100 μm.
