  • Look Inside

Significance probability mapping (SPM) of brain electrical activity first described by Duffy et al. isuseful tool for studying functional aspects of brain disease. Z-statistic SPM is able to identify the area of brain electrical activity deviated with statistic sig-nificance from the control group. The problem of this method is, however, that the nature of deviation, i.e., whether it is increase or decrease of electrical activity, can not he displayed. From this point of view, we attempted to use modified z-statistic method.
