Mean volume normalized cerebral blood flow (vnCBF) values for the left and right inferior frontal gyrus during syllable repetition by normal speakers (top), and these values following the subtraction of a resting state (bottom). Left and right side average flow values do not differ but subtracted flow values are significantly greater on the right side compared to the left side [t (51) = −3.283; p = .002].
