It is proposed that the direct pathway helps activate a specific movement. The indirect pathway counters this by inhibiting unwanted movements. This was shown most directly with optogenetic studies in which either the direct or indirect pathway was stimulated independently. Activation of the direct pathway facilitated movement (the example in the book is locomotion).
