Neuronal-level representations of speech production in inferior frontal gyrus

January 01, 2025

Conference Talk, BCI Society Meeting,

The role of the inferior frontal gyrus (IFG) in speech production remains poorly understood. Although lesion studies consistently implicate IFG in speech production, brain–computer interfaces that decode speech from this region have historically performed substantially worse than those using speech motor cortex. This discrepancy raises the question of what information IFG encodes during speech production.

Decoding speech intent from non-frontal cortical areas

Research Talk, Research in Progress, Department of Neurology, Chicago, IL

Brain–computer interfaces (BCIs) for speech restoration have largely focused on neural activity recorded from frontal speech motor regions, including ventral precentral cortex, postcentral gyrus, and inferior frontal gyrus. In contrast, temporal and parietal cortices are traditionally associated with speech and language perception, and their role in speech production remains unclear.
