Repository

This repository contains the data analysis scripts for Darks elicit gamma-band activity in the human retina and visual cortex with narrower bandwidth and faster propagation time than lights.

This paper is submitted, a pre-print can be found here.

The data analysis scripts are organized as follows:

Configuration file

• project_settings.m

Processing files

Preprocess and clean the data:

• preprocess_data.m
• clean_erg.m
• clean_meg.m

Prepare source localization:

• compute_headmodels.m
• compute_leadfields.m

Generate figures
