"Neural efficiency hypothesis" is one of the most common hypothesizes that is adopted to assess professional skills differences between experts and novices. When experts implement more familiar action skills that belong to themselves, they are more excellent than novices in four neural processes, neural efficiency, cortex expansion, professional process and inner model. In the sight of each frequency and EEG coherence indexes, differences in information processing changes that experts and novices make could be observed. According to motor learning process, this review was to examine practice differences in neural information processing that expert and novice make. Test the applicability of neural efficiency hypothesis from the results of EEG and offer neural efficiency hypothesis more reasonable explanations.
