Collection: Brain mechanisms underlying cue-based memorizing during free viewing of movie Memento

Description: This map shows all voxels that had their mean BOLD signal level increased during key-frames compared to cue-frames. This analysis is equivalent to GLM analysis with only constant and model regressors, i.e., correlation analysis. BOLD data was the same as used in RSA low/high-level analysis, except data was smoothed (5mm full-width half-maximum Gaussian kernel) before computing correlation. Correlation maps were Fisher transformed and entered into Randomize (FSL5.0) to perform one-sample permutation t-test (5000 iterations). Negative and positive values were analyzed independently and final map contains voxels that survived p<0.05 (two-tail, p<0.025 for each tail) with TFCE.

Warning: This map seems to be thresholded, sparse or acquired with limited field of view (99.92% of voxels are zeros). Some of the NeuroVault functions such as decoding might not work properly. Please use unthresholded maps whenever possible.
