Activity in the lateral prefrontal cortex reflects multiple steps of future events in action plans

Studies in which monkeys were asked to manipulate computer cursors for fruit juice rewards have revealed that the brain's "executive" center plans behaviors not by specifying movements required for given actions, but rather the events that will result from those actions.
