How do the eyes move together? New understandings help explain eye deviations in patients with stroke

Abstract

According to the 1-way callosal traffic theory, there is directionality in callosal traffic that is coded by handedness: motor signals travel strictly from the left to right in right-handed people and from the right to the left in neural left-handed people, using the anterior part of the callosum. Thus, the left eye, like all effectors on or toward the left side, is entirely controlled by the right hemisphere, with ultimate control remaining in the major hemisphere.
