Whole-Brain Millisecond-Scale Effective Connectivity of Auditory and Visual Naming.
Published September 14, 2026. Researchers mapped how brain regions exchange information during naming. The work adds useful detail to models of human speech, rather than demonstrating improved language treatment.

- Modalities
- EEG
- Clinical focus
- Language, Brain networks
- Population
- Patients performing auditory and picture naming during intracranial monitoring
- Sample
- 127 patients; 9,526 artifact-free, nonepileptic recording sites, not 9,526 people
- Intervention / method
- Transfer-entropy analysis of directional information flow, compared with stimulation mapping and response times
- Comparator
- Auditory versus visual naming; within-task timing and regional comparisons, not a treatment control
Clinician summary
Stronger time-specific information flows aligned with stimulation-induced symptoms and faster naming responses. Auditory and visual naming involved different pathway patterns.
How to interpret the findings
A selected intracranial-monitoring population limits generalization. Estimated connectivity is model-dependent; the study does not establish better surgical outcomes, neurofeedback efficacy or a validated noninvasive test. Follow-up and adverse events were unavailable in the abstract.
Equipment and disclosures
Intracranial EEG and electrical stimulation mapping; manufacturer not verified.
Funding and competing interests were not verified from the reviewed abstract.
