Figure 5: Inferior colliculus. Mean of TUNEL-positive cells and standard error in the central nucleus of the inferior colliculus 1 (7-day groups) or 2 weeks (14-day groups) after the initial noise exposure in the single (light gray) and double exposure groups (dark gray). Compared to 7-day groups, TUNEL was increased in the 14-day groups (asterisk). No differences in the incidence of TUNEL-positive cells were found between single and double-trauma group neither in the 7-day nor 14-day group (n.s.). n.s. = not significant; TUNEL = terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling.
