Haxby dataset

Access

See nilearn.datasets.fetch_haxby.

Notes

Results from a classical fMRI study that investigated the differences between the neural correlates of face versus object processing in the ventral visual stream. Face and object stimuli showed widely distributed and overlapping response patterns.

See Haxby et al.[1].
