Whole-Brain Dynamic Causal Tractography Atlas of Auditory and Visual Speech Networks Derived From Intracranial Neurophysiologic Data
These findings delineate dissociable white matter-mediated mechanisms, supporting rapid naming in auditory and visual domains. Reduced inhibitory monitoring by the right dorsolateral prefrontal cortex may facilitate efficient lexical retrieval through left perisylvian pathways during auditory naming, whereas excessive bifrontal interaction may underlie delayed auditory naming. Rapid visual object recognition seems to rely on early occipito-temporal coactivation with minimal Broca area involvement. The resulting atlas provides a resource for trainees studying the network dynamics underlying speech and for presurgical language mapping in patients undergoing cortical or subcortical interventions.
