Common cortical and thalamic mechanisms for language and motor functions.
Evidence for common mechanisms in the human brain for motor and language functions is reviewed, particularly evidence derived from electrical-stimulation mapping during cortical and thalamic operations in awake patients. Several systems in the dominant hemisphere are identified where language and motor function share common mechanisms, including a lateral thalamic attentional system and a lateral perisylvian cortical system common to sequential movement and speech sound identification, where precise timing may be a common mechanism.
