About ofc-3

Information about ofc-3 (orbitofrontal cortex, number 3).


This dataset contains electrocorticography (ECoG) recordings from the orbitofrontal cortex (OFC) of n=10 neurosurgical patients being operated on for the treatment of epilepsy. During the ECoG recordings, patients played a simple decision-making task (a gambling game) – the behavior and timestamps of the relevant events are also provided. Recordings last ~15min on average, each including 200 behavioral trials.  The data are described in:

Ignacio Saez, Jack Lin, Arjen Stolk, Edward Chang, Josef Parvizi, Gerwin Schalk, Robert T. Knight, Ming Hsu; Encoding of Multiple Reward-Related Computations in Transient and Sustained High-Frequency Activity in Human OFC; Current Biology, Volume 28, Issue 18, 24 September 2018, Pages 2889-2899.

Format of the data.

The ECoG data is stored in .mat files and the behavioral data in CSV files. Details of the format are provided in the data description document (link at bottom of this page).  Total size of the data is about 786 MB.
