Activity in Broca's area during speech‐reading. A: activation patterns for each subject group and differential activation pattern between NH controls and patients at T0. B: normalized regional cerebral blood flow (arbitrary units) in the left posterior middle frontal gyrus for each subject group. Activity level in Broca's area increases with the auditory experience, being low for inexperienced cochlear‐implant patients and high for NH controls. Panel C shows the individual differences of activity between T0 and T1 (7 paired comparisons; the single outlier is a different patient than the one in Fig. 2C).
