Description of dataset vim-2 (visual imaging 2).

Summary of the data

This data set contains BOLD fMRI responses in human subjects viewing a set of natural movies.  The functional data were collected for three subjects, in three sessions over three separate days for each subject.  Details of the experiments are described in the original publication about this data:

Nishimoto, S., Vu, A. T., Naselaris, T., Benjamini, Y., Yu, B., & Gallant, J. L. (2011). Reconstructing visual experiences from brain activity evoked by natural movies. Current Biology, 21(19), 1641-1646.

Format of the data

The response from each subject is provided in a separate MatLab file, and all Stimuli are provided in a single MatLab file.  These files are stored in Matlab version 7.3 format, which is hf5 format compatible and can be read directly into numpy/python using the PyTables library.  Anatomy information for each subject is provided in a fMRI image file in Nifti (.nii) format.  Details about the data files are given in document crcns-vim-2-data-description.pdf.  Total size (compressed) of the data is about 13 GB.
