About vim-3

Description of dataset vim-3 (visual imaging 3).

Summary of the data

The data set has functional magnetic resonance imaging (fMRI) measurements of the magnitude of evoked activity in the visual areas V1, V2, and V3 in seven humans in response to image patches, drawn from above or below the centre of gaze of an observer navigating a natural environment.  The experiments and data are described in the following paper:

Mannion DJ. (2015) Sensitivity to the visual field origin of natural image patches in human low-level visual cortex. PeerJ 3:e1038 https://dx.doi.org/10.7717/peerj.1038

Format of the data

The response from each subject is provided in a separate directory and includes the 10 fMRI recordings, in NIFTI format, in addition to the sequence and behavioural task information, in NumPy format.  Details about the data files are given in document crcns_vim-3-data_description.pdf.  Total size (compressed) of the data is about 2.2 GB.
