Middle latency auditory responses in males who stutter.

Little research exists that explores subcortical function in people who stutter. One study suggested that auditory middle latency response Wave Pb was prolonged in subjects who stutter as compared to controls. Other studies have suggested that Pb was generated within the thalamic portion of the reticular system. MLRs were recorded from 10 males who stutter and 10 controls using a variety of filter passbands in response to clicks presented binaurally at various rates. The latency of Pb was found to be significantly shorter in the group of subjects who stutter.
