    abstract = {Parallel, largely segregated, closed-loop projections are an important component of cortical-basal ganglia-cortical connectional architecture. Here, we present the hypothesis that such loops involving the neocortex are neither novel nor the first evolutionary example of closed-loop architecture involving the basal ganglia. Specifically, we propose that a phylogenetically older, closed-loop series of subcortical connections exists between the basal ganglia and brainstem sensorimotor structures, a good example of which is the midbrain superior colliculus. Insofar as this organization represents a general feature of brain architecture, cortical and subcortical inputs to the basal ganglia might act independently, co-operatively or competitively to influence the mechanisms of action selection.},

McHaffie et al. describe subcortical loops, and in particular loops involving the SC, through the basal ganglia.

McHaffie et al. speculate that loops through various subcortical loops might solve the selection problem, ie. the gating of competing inputs to shared resources.

In the SC, this means that the basal ganglia decide which of the brain structures involved in gaze shifts access to the eye motor circuitry.
