Two brains, one clock.
A recent study has shown that information about the duration of brief time intervals acquired by one side of the brain is readily available to the other cerebral hemisphere in a patient in which the corpus callosum and the other forebrain commissures have been sectioned. This strongly suggests that the internal clock that measures time duration is subcortical, and that its output can be easily projected to both hemispheres via subcortical commissures.
