Abstract :
The purpose of the present study was to demonstrate the power of significance probability mapping in localizing EEG slowing in Alzheimer´s Disease (AD) patients relative to a control group. The t-statistic mapping was used to highlight the common pattern changes in AD patients, and the z-statistic mapping served to show the diversity of impairments in these patients
