According to Ratcliffe-Baird (2008), relative to healthy controls, stutterers show:: Hypercoherence across 25 – 30Hz bands over Broca’s area.; More frontal theta and low alpha activity than nonstutterers when at rest and during tasks that require selective inhibition of attention to competing stimuli.; Hypocoherence between F7 and F8 across 1-9Hz when asked to inhibit stuttering while talking.; High measures of asymmetry in the alpha band when at rest, as well as during selective inhibition task.
