By usingoddballparadigm andexperts-novicesparadigm,electrical activity of brain was recorded in the process of table tennis athletes' judging serve rotation on the base of single feature pictures. The results show that there were obviously differences in the whole brain's activated order and level between second grade table tennis athletes( experts) and majoring college students( novices). C1and P1 components are induced in occipital region,N1 in central region and P3 in the every region; for table tennis athletes,in the phase of perception for single feature information,cerebral cortex is activated at higher level in comparison with novices,athletes' brain plasticity probably occurred because of long term exercise training,which is very sensitive to physical features of relevant movement stimuli; in the phase of recognition,cerebral cortex is activated also at higher level with faster recognition speed,and mental resource is devoted more.
