Recent brain scan research has found abnormalities in the brains of stutterers and promises new treatments for stuttering using drugs and computerized devices No differences between stutterers and non-stutterers have been found during silent rest Ingham 1996 During fluent speech stutterers brains look similar to non-stutterers brains But during stuttering cerebral activity changes dramatically The most striking difference is that left-hemisphere areas active during normal speech become less active and areas in the right hemisphere not normally active during speech become active Braun 1997 Ingham 1997 This abnormal right-hemisphere dominance has produced a variety of speculative hypotheses from researchers Note that brain scans can show relative activity in different areas of the brain but cant show what the person is thinking or what each area is doing Researchers often hypothesize on the functions of various brain areas but this is at best educated speculation One hypothesis is that there is something wrong with stutterers left-brain speech areas and so right-brain areas not developed for speech take over This seems unlikely given that most stutterers are capable of normal fluent speech in some conditions Another hypothesis is that the right-hemisphere activity is the fears and anxieties that stutterers experience generated by the limbic and paralimbic structures But these areas dont seem to be abnormally active during stuttering Another hypothesis is base on the decreased central auditory processing during stuttering seen in all studies Wu 1995 Fox 1996 Ingham 1997 One study also found decreased activity in the area that integrates auditory and somatic body sensation Braun 1997 These are all rear-brain areas The researchers hypothesized that stuttering reduces this rear-brain sensory processing and reduces the left-brain communication of this sensory information to frontal speech and language areas The abnormal right-brain activity may be an alternative pathway for rear-brain sensory information to travel to the front of the brain Another team of researchers believes that the key to stuttering lies in the different functions of the lateral
