The orofacial motor cortex controls the split-second timing needed for coordinated duet singing. Song content and song timing are handled separately in the brain systems described by the research. Cooling the OMC slowed nerve activity and made songs longer, implying that normal OMC activity regulates timing and duration. Drug silencing of the OMC prevented coordinated call-and-response singing.
