WebCorticomuscular coherence is tuned to the spontaneous rhythmicity of speech at 2–3 Hz. Human speech features rhythmicity that frames distinctive, fine-grained speech patterns. Speech can thus be counted among rhythmic motor behaviors that generally manifest characteristic spontaneous rates. WebApr 28, 2024 · The frontal lobe has an area called Broca’s area located in the posterior inferior frontal gyrus involved in speech production. A recent study shows that the exact function of Broca’s area is to mediate sensory representations that originate in the temporal cortex and going to the motor cortex.
