RealFeedApp Reduced speech-brain coherence in left supramarginal gyrus for children with DLD
The study found reduced brain coherence in the 0.9–2.5 Hz range for children with developmental language disorder, impairing their ability to process prosody and syllables.
- Field
- the brain and neuroscience
- What they did
- Researchers recorded brain magnetic activity in children with and without a developmental language disorder while they listened to a story to check how they track slow speech rhythms. Children with the disorder showed significantly reduced brain-speech connection in the 0.9–2.5 Hz frequency range, which relates to the rhythmic structure of speech.
- Why it matters
- This helps explain why children with this disorder struggle to learn language, as their brains process basic rhythmic patterns needed for speech structure formation less effectively.
