Oscillatory electroencephalographic patterns of arithmetic problem solving in fourth graders

Abstract Numerous studies have identified neurophysiological correlates of performing arithmetic in adults. For example, oscillatory electroencephalographic (EEG) patterns associated with retrieval and procedural strategies are well established. Whereas fact retrieval has been linked to enhanced lef...
