Supplementary Eye Fields (SEF)

As in our superior colliculus experiments, we used microstimulation to show that the 3-D transformations for eye-head coordination are implemented downstream from the SEF. However, unlike the superior colliculus, we found that different SEF sites encode gaze shifts in different frames, mostly in eye or head-fixed frames, but in other frames as well. Currently we plan to use multi-unit recordings to understand how different visual signals can organizes these frames of reference to implement complex gaze behaviors.
