A common mechanism for the control of eye and head movements in humans

Ann Neurol. 2000 Jun;47(6):819-22.

Abstract

How the human brain controls the subtle coupling between eye and head movements is still debated. The brain could either coordinate two separate (eye and head) networks or use a single system involved in gaze (eye + head) control. In a recent report, a total transfer from eye to head movements was observed in a patient with congenital ophthalmoplegia. This led the authors to hypothesize that such transfer resulted from a long-term adaptation between oculomotor and head movement systems. We report on a patient in whom a similar transfer was observed but at the acute stage of an acquired ophthalmoplegia. This case demonstrates that the transfer between head and eye movements does not necessarily require long-term adaptation and supports the hypothesis of a common unique gaze motor command in which eye and head movements would be rapidly exchangeable.
