ofc-3 – Frequency content of the electrophysiology data

Hello,

Thank you for making the ofc-3 dataset (https://crcns.org/data-sets/ofc/ofc-3) available.

The accompanying documentation states that the electrophysiology data consists of ‘HG activity’. Accordingly, all variable names in the electrophysiology files consist of the acronym ‘hg’. However, I could not find the expansion of ‘hg’ in the document. I suspect that it refers to ‘high-gamma’ given that the original study examined high-frequency activity (HFA; 70-200 Hz), and the preprocessing methods suggest that the data may have been filtered into this frequency range. Can the authors please confirm whether the data uploaded to the repository has been filtered into this frequency range (70-200 Hz) or whether it consists of information from any other frequencies?

Thank you,

Hi Shrey,

Thanks for your interest in the dataset. Your deduction is correct - the data is coded as hg as per high gamma, and it corresponds to the HFA referred to throughout the manuscript (70-200Hz).

Hi Ignacio,

Thank you for confirming that!
