3. whole head anatomy - T1w 3D MPRAGE. Matrix size 256 x 256, 160 slices. Reconstructed as sagittal images. voxel size 1 mm isotropic. TE 3.7 ms, TR 8.13 ms, FA 8°, TI 960 ms, and linear phase encoding order.

Stimulus set-up

• stimuli were presented on a BOLDscreen (CRS Ltd, Rochester, UK) - https://www.crsltd.com/tools-for-functional-imaging/mr-safe-displays/boldscreen-32-lcd-for-fmri/
• 2018/19 stimulus code: inspect scene_localiser() in the stimulusCode directory. If you can’t run the code and get errors, have a lootk at this clip on youtube to get an impression.
• other details have remained the same since the 2017/18 version.
