Turn-taking is a central feature of conversation across languages and cultures.1 , 2 , 3 , 4 This key social behavior requires numerous sensorimotor and cognitive operations1 , 5 , 6 that can be organized into three general phases: comprehension of a partner's turn, preparation of a speaker's own turn, and execution of that turn. Using intracranial electrocorticography, we recently demonstrated that neural activity related to these phases is functionally distinct during turn-taking.7 In particular, networks active during the perceptual and articulatory stages of turn-taking consisted of structures known to be important for speech-related sensory and motor processing,8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 while putative planning dynamics were most regularly observed in the caudal inferior frontal gyrus (cIFG) and the middle frontal gyrus (cMFG)...
