We have a new paper in press in the international journal, Philosophical Transactions of the Royal Society B: Biological Sciences. This paper was part of a collaboration between us and Prof. Richard Krauzlis from the National Eye Institute, USA and Prof. Laurent Goffart from CNRS, France.
The paper describes an interesting perspective on the neuronal control of gaze fixation and fixational eye movements. We present a framework for thinking about gaze fixation that allows reconciling a wide variety of experimental observations not only about gaze fixation, but also about the small microscopic eye movements that occur incessantly during such fixation. We particularly discuss the roles of the superior colliculus (SC) and cerebellum, and we highlight some intriguing unanswered questions that we hope will motivate further research in the future.
