Little research exists that explores subcortical function in people wh
o stutter. One study suggested that auditory middle latency response W
ave 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 respon
se to clicks presented binaurally at various rates. The latency of Pb
was found to be significantly shorter in the group of subjects who stu
tter.
