Passive sound exposure alters frequency tuning in the aged A1. A, Representative A1 CF maps from naïve rats (top) and from rats exposed to 5-kHz pure tones during 1 week (bottom). D, dorsal; C, caudal; R, rostral; V, ventral. B, Difference in frequency tuning between naïve and exposed rats expressed as A1 percentage area and separated by CF for immature, young adult, and old adult groups. Immature group: n = 8, recorded sites = 389; YA: n = 8, recorded sites = 403; OA: n = 8, recorded sites = 382; immature-exposed: n = 8, recorded sites = 362; YA-exposed: n = 4, recorded sites = 177; OA-exposed: n = 4, recorded sites = 168. Values shown are mean, two-way ANOVA with Tukey–Kramer correction.
