A) The monkey associates with each target of a different shape a different probability of obtaining a reward. He is shown two targets. To optimise his reward, he must choose the target associated with the higher probability of obtaining a reward. His choice is visualised by shifting the cursor (x) across the screen towards the chosen target. In this example, the target situated at 0° ($$) is more interesting that that at 90° ($). The diagram on the right shows the striatum and internal globus pallidus, the structures implicated in movement: to the right (0°) or towards the top (90°). B) Dopamine informs the basal ganglia in the striatum about the
