✦ Synopsis


FM'RI with standard 1.5 T scanners requires adapted algorithms because the time course of intensity signal showed a non-linearity of tbe baseline. The protocol contains scqaenttal images cover& periods of rest followed periods of stimulation. The images of each period of rest and stimulation were averaged, offering a series of averaged images. From this series, we conserved only tbe pixels which presented the alternated variations conaspomdhg to the temporai pattern of the paradigm. A coloor scale was osed to present the average percentage of variations of each pixel selected. We have performed activation paradigms with a cla&cai motor protocol. This simple %How+p" method appears effective for the identifications of activated areas. 0 l9!77 Ek&er Science Ltd.

Although functional magnetic resonance imaging (fMRI) methods yield rich temporal and spatial data for even a single subject, universally accepted data analysis techniques have not been developed that use all the potential information from fMRI of the brain. Specifically, temporal correlations and c
