Debate: Do Split Brain Patients Have Two Minds?

In split-brain patients, the cerebral hemispheres have been separated by severing the corpus collosum. These patients sometimes behave as if they have one mind and sometimes as if they have two. Do these patients have a single consciousness that is in some respects fragmented? Or does each hemisphere support a distinct experiencing subject with a separate mind?

Elizabeth Schechter, author of the recent book Self-consciousness and ‘Split-brains’: The Mind’s I, will argue for the two-minds view. Yair Pinto, author of the recent article “The Split Brain Phenomenon Revisited: A Single Conscious Agent with Split Perception”, will argue for the one-mind view. Joseph Ledoux, author of the 1977 article “A Divided Mind: Observations on the Conscious Properties of the Separated Hemispheres”, will argue for an intermediate position.
