The authors provide a theoretical framework for viewing stuttering as a disorder of timing. Evidence is reviewed from neuroimaging and brain stimulation experiments that show a great degree of overlap between the structures engaged in the internal timing of movements and the regions thought to be causally involved in stuttering. The authors provide evidence of overlap between the neural structures engaged in the external timing of movement and link them with compensatory activity in people who stutter. Significant gaps in literature are highlighted.
