Miyawaki 2008 dataset

Access

See nilearn.datasets.fetch_miyawaki2008.

Notes

Collection of result images from MVPA investigation of the human visual systems.

This fMRI study reconstructed visual images by combining local image bases of multiple scales. Their contrasts were independently decoded from fMRI activity by selecting important voxels and capitalizing on their correlation structure.

See Miyawaki et al.[1].

Content

‘label’:

Paths to text files containing run and target data

‘func’:

Paths to nifti files with BOLD data

‘mask’:

Path to general mask nifti that defines target volume in visual cortex

‘mask_roi’:

List of paths to images with specific data (‘RH’ for right hemisphere, ‘LH’ for left hemisphere, ‘Vxxx’ denote visual areas)
