Abstract
Brain activity synchronization is believed to play a major role in human learning, as it emerges from the integration of several brain processes that bind together different sensory inputs. In this study, we used dense-array recordings of electroencephalographic (EEG) activity during execution of a complex learning task to possibly identify patterns of brain activation that correspond to distinct phases of learning. Our results show that subjects who go through both phases of learning, namely strategy formulation and strategy implementation, exhibit very strong long-range synchronization between occipital and frontal brain regions primarily in the gamma band, while the rest of the subjects exhibit patterns of weak local synchronization in all bands.
