This study investigates how the superior colliculus couples target selection and acquisition in mice, showing that choice-predictive neurons increase activity during movement and that an attractor model explains the rostral shift in activity during target acquisition.

The paper investigates how direct and indirect sensory cues influence dual-adaptation learning, finding that visual workspace location cues enable implicit adaptation while color cues rely on explicit strategies.
