The paper identifies how value signals influence different neuron subtypes in the superior colliculus to modulate saccadic vigor during eye movements.

This study uses retrograde optogenetics in macaques to show that FEF outputs to the superior colliculus are diverse but predominantly motor-related, supporting a visuomotor convergence model.

The paper tests whether saccadic eye movements are controlled by a velocity-based internal feedback controller using optimal control models, finding that a velocity tracking model better explains velocity modulation during eye-hand coordination.
