The speech production network relies on a widely distributed brain network. However, research and development of speech brain-computer interfaces (speech-BCIs) has typically focused on decoding speech only from superficial subregions readily accessible by subdural grid arrays-typically placed over the sensorimotor cortex. Alternatively, the technique of stereo-electroencephalography (sEEG) enables access to distributed brain regions using multiple depth electrodes with lower surgical risks, especially in patients with brain injuries resulting in aphasia and other speech disorders.

- Language and music share a productive combination of basic units, but it's uncertain if the brain areas for both are the same.
- In a study involving a musician, researchers used cortical stimulation mapping and electrocorticography to analyze how the brain perceives and produces music and language during specific tasks.
- Results showed that the posterior superior temporal gyrus (pSTG) is crucial for both music and speech production, but different complexities in music and language activate distinct neural responses in the brain.
Objective: Resective surgery in language-dominant ventral occipitotemporal cortex (vOTC) carries the risk of causing impairment to reading. Because it is not on the lateral surface, it is not easily accessible for intraoperative mapping, and extensive stimulation mapping can be time-consuming. Here the authors assess the feasibility of using task-based electrocorticography (ECoG) recordings intraoperatively to help guide stimulation mapping of reading in vOTC.
