NIRSTORM: a Brainstorm plugin specialized in the analysis of fNIRS data
Author: Édouard Delaire, Lea Larreur, Dr. Zhengchen Cai, Dr. Christophe Grova
This tutorial aims to introduce NIRSTORM. NISTORM is a plug-in dedicated to the analysis of functional near-infrared spectroscopy (fNIRS) data inside Brainstorm. This tutorial will cover three main aspects of NIRSTORM: (1) Data importation and preprocessing, (2) Data analysis at the channel level, and (3) Data analysis on the cortical surface. This tutorial assumes that you are already familiar with the Brainstorm environment. If you are not, we encourage you to follow the tutorial 1 to 23.
Introduction
Presentation of the experiment
• One subject, one run of 19 minutes acquired with a sampling rate of 10Hz on a CW fNIRS Brainsight device (Rogue-Research Inc., Montreal, Canada) • Finger tapping task: 20 blocks of 10 seconds each, with a rest period of 30 to 60 seconds. • 3 sources, 15 detectors, and 1 proximity detector. • 2 wavelengths: 685nm and 830nm • 3T MRI anatomy processed by FreeSurfer 5.3.0.
