4.3 Multi-Subject FMRI data

Five healthy right-handed subjects perfomed 30s blocks of a visually cued reaction time task involving left index finger movement, left hand sequential finger movement and left hand random finger movement (see [Johansen-Berg et al., 2002] for details).

For each subject, 122 axial echo-planar volumes (21x6mm slices, TE=30ms, TR=3s, 64*64*21 voxels at 4x4x6mm) were acquired on a 3T Varian/Siemens MRI system at the Oxford Centre for Functional Magnetic Imaging of the Brain together with a T1-weighted anatomical image at 1x1x1.5mm resolution.
