Abstract

In a systematic study of hybrid MR time-series with simulated "activation"(contrast-to-noise range 1-10) we investigated the power and compared the ability of the "novelty indices" (NI) kurtosis, negentropy, and 1-lag autocorrelation, to discriminate between potentially interesting ("structured") and uninteresting ("noisy") tirne-courses (TCs). NIs may he employed as preprocessing tools to focus only on the interesting TCs prior to any further exploratory or confirmatory approach. (C) 2000 Elsevier science Inc. All rights reserved.
