Description

The fMRI data provided here have been used to study the visual system under the natural vision paradigm. Specifically, the data have been used to 1) explore the potential confounds of this paradigm (Lu et al., 2016) and 2) investigate the structure of the BOLD signal observed in white matter using natural vision (Marussich et al., 2017).

Thirteen subjects underwent four fMRI sessions with two conditions. Two sessions were obtained in the eyes-closed resting state, and the other two sessions occurred during free-viewing of an identical movie clip The Good, the Bad, and the Ugly, 1966, from 162:54 to 168:33 min. in the film). The visual input was presented using the MATLAB Psychophysics Toolbox, and they were delivered to subjects through a binocular goggle system (NordicNeuroLab, Norway) mounted on the head coil.  Each movie-stimulation (task) session began with a blank gray screen presented for 42 s, followed by the movie presented for 5 min and 37 s, and ended with the blank screen again for 30 s. The resting-state sessions had the same duration as the movie-stimulation sessions.

Notes

Whole-brain structural and functional MRI images were acquired using a 3-Tesla Signa HDx MRI system (General Electric Health Care, Milwaukee, USA). Briefly, the fMRI data were acquired using a single-shot, gradient-recalled (GRE) echo- planar imaging (EPI) sequence (38 interleaved axial slices with 3.5mm thickness and 3.5 × 3.5 mm2 in-plane resolution, TR=2000 ms, TE=35 ms, flip angle=78°, field of view=22×22 cm2). T1-weighted anatomical images covering the whole head were acquired with a spoiled gradient recalled acquisition (SPGR) sequence (1×1×1mm3 nominal resolution, TR/TE=5.7/2 ms, flip angle=12°). A 16-channel receive-only phase array coil (NOVA Medical, Wilmington, USA) was used during all acquisitions.
