About pfc-5

Information about pfc-5 (prefrontal cortex, number 5).

Summary.

This data set contains human scalp EEG recordings from 14 patients with unilateral prefrontal cortex lesions (mean ± SD [range]: 46 ± 16 [20-71] years of age, 15 ± 3 years of education, 6 males) and 20 age- and education-matched, healthy controls (44 ± 19 [19-70] years of age, 16 ± 3 years of education, 11 males). Primary (raw) and derived (preprocessed) EEG data, and analysis scripts are included.  Methods, participants, and results are described in:

Johnson, E. L., Dewar, C. D., Solbakk, A-K., Endestad, T., Meling, T. R. & Knight, R. T. Bidirectional frontoparietal oscillatory systems support working memory. Current Biology 27, 1829-1835 (2017). doi:10.1016/j.cub.2017.05.046

Format of the data.

Primary EEG data files are in .bdf (BioSemi) format. These files may be imported and converted to .mat format. Processed data is in .mat format. Information about each PFC patient subject is stored in .csv format. Total size of the data is about 20 GB. Details about the data are in the document linked to at the bottom of this page.

How to download the data.

The data must be downloaded from:

https://portal.nersc.gov/project/crcns/download/pfc-5

A CRCNS.org account is required.  This link allows bulk downloading of multiple files using the download script as described in the "Alternative download method" section on the download page.

Getting help using the data.
