Naturalistic speech elicits an ABR-MLR complex with a very early cortical peak at 11 ms latency in adults, which is absent for click stimuli.
- Why it matters: The dependence of auditory brainstem and middle-latency responses on stimulus complexity and behavioral relevance is not well characterized.
- What they did: Adults were recorded with simultaneous EEG and MEG while listening to naturalistic speech and clicks, and temporal response functions (TRFs) were computed to compare ABR-MLR and MLR components.
- The result: Speech-specific differences include an 11 ms cortical peak and distinct latency/source patterns in thalamus and cortex, while both speech and click ABR complexes share a prominent wave V response.
