Brain Recordings

Led by researchers at NYU Grossman School of Medicine, the study results add to evidence that neighboring brain regions, the inferior frontal gyrus and the motor cortex, play an important role in such planning before words are said aloud. Both are part of the folded top layers of the brain, or cerebral cortex, which has long been known to control the muscle (motor) movements in the throat and mouth needed to produce speech. Less clear until now was how closely these regions determine the mix of sounds and words people want to say aloud, the authors report.
