MRI Motion Tracking Data (EEG&SPM)

The dataset contains synchronized free-running EPI MRI data and gradient-induced voltage recordings acquired from a healthy human volunteer using a Philips Achieva 3T scanner. Five small electromagnetic coils were mounted on an EEG-like cap, and voltages were recorded at 5 kHz using a BrainAmp MR-compatible amplifier. MRI data include 150 volumes of ungated EPI (TE = 40 ms, TR = 2 s, 25 slices, 3\u00d73\u00d73 mm\u00b3 resolution), collected during both a model-formation period with cued head movements and an experimental period with natural free movements. The dataset also provides synchronized waveform templates, modeling intervals, coil positions, and SPM8-derived motion parameters to support research in prospective motion correction, gradient-based motion characterization, and head-motion modeling. All data were acquired under IRB approval and are anonymized for public release.
