Abstract. In a reward-seeking task performed in a continuous environment, our
previous work compared several Actor-Critic (AC) architectures implementing
dopamine-like reinforcement learning mechanisms in the rat's basal ganglia.
The task complexity imposes the coordination of several AC submodules, each
module being an expert trained in a particular subset of the task. We showed
