A gaze controller fusing sensory and reafference signals. A: proposed schematic interconnecting eye and head centers, in response to a flashed target distance (ΔG). B: embedding cerebellar pathways in this reduced gaze controller, i.e., effects of parallel or feedback processes can be reflected in parameter choices for the simplified pathways. See Fig. 2 for more details on bidirectional interactions between cerebellum and brain stem at all levels of gaze control. See glossary for definitions.
