Differential cortical and subcortical visual processing with eyes shut

This dataset contains raw 3T fMRI data from 8 subjects who completed a visual task with their eyes open or closed. Visual stimulus was a full-field flickering stimulus with no spatial contrast with a 16 second on-off block design. On blocks were either a high temporal contrast trial, with 100% contrast modulation flickering from a completely white to black screen at 7Hz, or a low temporal trial, with a 10% contrast modulation flickering between midling grey intensities at 7Hz. Off blocks were non-flickering median luminance screens.
