About vim-4

Summary of the data

This dataset contains data from two tasks: a visual attention task, and a video game task. In both tasks, fMRI was used to record whole-brain BOLD activity with a 2.0045 s TR from healthy human subjects.

In the visual attention task, subjects watched naturalistic movies in different attentional states. Each subject watched 2 hours of naturalistic movies passively, 30 minutes while attending to the presence of humans, and 30 minutes while attending to the presence of vehicles. The movies used in the attend-human and attend-vehicle conditions were identical, and was subsampled from the 2 hours of movies used during passive viewing.

In the video game task, subjects played Counterstrike: Source. The gameplay was open-ended. Because this data was originally collected as part of a pilot, subjects played for different amounts of time. One subject played for 90 minutes, and the other subject played for 45 minutes.

Data from the visual attention task was used in the following publications:

• Çukur, Tolga, Shinji Nishimoto, Alexander G. Huth, and Jack L. Gallant. 2013. “Attention during Natural Vision Warps Semantic Representation across the Human Brain.” Nature Neuroscience 16 (6): 763–70.
• Zhang, Tianjiao, James S. Gao, Tolga Cukur, and Jack L. Gallant. 2020. Voxel-based state space modeling recovers task-related cognitive states in naturalistic fMRI experiments. Submitted to Frontiers in Neuroscience.

Data from the video game task was used in the following publication:

Zhang, Tianjiao, James S. Gao, Tolga Cukur, and Jack L. Gallant. 2020. Voxel-based state space modeling recovers task-related cognitive states in naturalistic fMRI experiments. Submitted to Frontiers in Neuroscience.

S4 is not included as the subject did not consent to the public release of their data.

Format of the data

The data are stored in HDF5 containers in numpy arrays. Details about the data files are given in document linked to at the bottom of this page. Total size of the data is about 15 GB.
