Figure 5

Cortical surface area is decreased due to hearing loss in HG (apparent when groups with mild and expressed presbycusis are compared). HG surface area is larger on the left side (laterality). The effect of hearing loss on surface area of HG is independent of the laterality. Only data from aged groups are used and are pooled together based on the degree of presbycusis; right and left include data from right and left HG. Data are compared based on M3 (only elderly groups). *p < 0.05 uncorrected.
