Abstract: Over the past decade, a number of neuroimaging studies have demonstrated that human skill learning is a dynamic process, in which at least two phases of changes in regional brain activity are observed. In the early phase, activity decreases over the learning probably due to the increase of neuronal selectivity, whereas in the late phase activity increases because of the recruitment of new neurons. Changes in brain activity are modulated by awareness of learning tasks and switching of strategies. At the same time, regional connectivity is developed and gradually strengthened, resulting in a temporarily task-oriented system. This system is controlled and modulated by high-order associative areas such as the frontal cortex.
