Summary
Research on stuttering subcortical function is limited. This study found that the auditory middle latency response Wave Pb was significantly shorter in males who stutter compared to controls, suggesting altered subcortical processing.
Area of Science:
- Neuroscience
- Speech and Hearing Sciences
Background:
- Subcortical function in individuals who stutter (PWS) is under-researched.
- Previous research suggested prolonged auditory middle latency response (MLR) Wave Pb in PWS, potentially linked to the thalamic reticular system.
Purpose of the Study:
- To investigate subcortical auditory processing differences in PWS.
- To explore the latency of the auditory middle latency response Wave Pb in males who stutter.
Main Methods:
- Recorded middle latency responses (MLRs) from 10 males who stutter (PWS) and 10 controls.
- Utilized various filter passbands and binaural click stimuli at different presentation rates.
Main Results:
- The latency of Wave Pb was significantly shorter in the PWS group compared to the control group.
- This finding contrasts with previous research suggesting prolonged Pb latency.
Conclusions:
- Subcortical auditory processing, specifically the MLR Wave Pb, appears to be different in males who stutter.
- The shorter latency suggests potentially faster or altered neural transmission within the auditory pathways in PWS.
