4.2 Multi-Session FMRI data

The data were originally used in [McGonigle et al., 2000] to study session variability in repeated FMRI experiments: a healthy 23-year old right handed male was scanned under a visual, cognitive and motor paradigm in 33 separate sessions over a period of 2 months. The data used here consists of the first 10 sessions under the motor paradigm: a block design with 24.6s on/off periods and right index finger tapping at 1.5 Hz during the 'active' condition. Data (78 volumes) was collected on a Siemens Vision (2T) with TR=4.1s, 48*64*64 (3mm isotropic voxels). In addition, a single T1 weighted structural image was taken at 1x1x1.5mm resolution.
