Objective Measuring electrical signal of EEG,ECoG,ERP and picking up brain induce characteristic signals we needed,then studying person's various behaviors and diseases are the important method of brain nerve theories and experiment research.Methods Because the brain electric signals are very weak,usually in the micro volts,so noise deduction processing for the observed data,picking up characteristic signal is one of the front techniques in the clinic and experiment research.Through long-term investigation,noise deduction method were put forward.Results On the basis of mathematical model which we established,the MATLAB method was used to analyze original data in the experiment and get rid of noise efficiently.It provides a set of fast,convenient,accurate brain electrical signal noise deduction method.
