Deficits in reach target selection during inactivation of the midbrain superior colliculus Proceedings of the National Academy of Sciences, Vol. 108, No. 51. (20 December 2011), pp. E1433-E1440, doi:10.1073/pnas.1109656108 by Joo-Hyun Song, Robert D. Rafal, Robert M. McPeek

    abstract = {Purposive action requires the selection of a single movement goal from multiple possibilities. Neural structures involved in movement planning and execution often exhibit activity related to target selection. A key question is whether this activity is specific to the type of movement produced by the structure, perhaps consisting of a competition among effector-specific movement plans, or whether it constitutes a more abstract, effector-independent selection signal. Here, we show that temporary focal inactivation of the primate superior colliculus ({SC}), an area involved in eye-movement target selection and execution, causes striking target selection deficits for reaching movements, which cannot be readily explained as a simple impairment in visual perception or motor execution. This indicates that target selection activity in the {SC} does not simply represent a competition among eye-movement goals and, instead, suggests that the {SC} contributes to a more general purpose priority map that influences target selection for other actions, such as reaches.},

The SC may play a major role in the selection of stimuli—as saccade targets or as reaching targets.
