How does your brain decide what you will do next? Over the past few decades\ncompelling evidence has emerged that the basal ganglia, a collection of nuclei\nin the fore- and mid-brain of all vertebrates, are vital to action selection.\nGurney, Prescott, and Redgrave published an influential computational account\nof this idea in Biological Cybernetics in 2001. Here we take a look back at\nthis pair of papers, outlining the "GPR" model contained therein, the context\nof that model's development, and the influence it has had over the past twenty\nyears. Tracing its lineage into models and theories still emerging now, we are\nencouraged that the GPR model is that rare thing, a computational model of a\nbrain circuit whose advances were directly built on by others.\n
