Talha Soluoku (Neuroscience) and James M. Hyman (Psychology) recently published an article in Neuron titled, "Complexity demands more flexibility and the prefrontal cortex has an answer." This article provides context about a recent finding showing that in tasks with greater complexity, the medial prefrontal cortex helps to switch between procedural behavior guided by the dorsolateral striatum and deliberative behavior controlled by the hippocampus.
