10 subjects were scanned with fMRI during a "language localizer" where they (covertly) read meaningful sentences (trial_type='language') or strings of consonants (trial_type='string'), presented one word at a time at the center of the screen (rapid serial visual presentation).
The functional images files (in derivatives/) have been preprocessed (spatially realigned and normalized into the MNI space). Initially acquired with a voxel size of 1.5x1.5x1.5mm, they have been resampled to 4.5x4.5x4.5mm to save disk space.
