Significantly increased variability to speech sounds, tones, letters, and shapes in left hemisphere outside primary auditory cortex. Error bars are standard error of the mean. * unpaired one-tailed t-tests at p < 0.05 after Bonferroni correction. Horizontal lines without * indicate nominally significant comparisons that did not survive multiple-comparisons correction. A-D. Variability to auditory (A-B) and visual (C-D) stimuli in left inferior frontal gyrus (IFG). E-H. Variability to auditory (E-F) and visual (G-H) stimuli in left superior temporal gyrus (STG).
