Multi-step planning in the brain

Decisions in the natural world are rarely made isolation. Each action that an organism selects will affect future situations which it finds itself, and those turn actions available. Achieving real-world goals often requires successfully navigating a sequence of many actions. An efficient flexible way to achieve such is construct internal model environment, use plan behavior multiple steps into future. This process known as multi-step planning, its neural mechanisms only beginning be understood. Here, we review recent advances our understanding these mechanisms, take advantage decision tasks for humans animals.
