We are pleased to welcome Dr. David Boas to share with us his expert knowledge on the topic of High-Density fNIRS (HD-fNIRS / DOT). HD-fNIRS is a methodology that employs high-density arrays with short, medium and long channels. Overlapping measurements with multiple source-detector distances can improve spatial resolution, depth and lateral specificity, and can enable the tomographic (image) reconstruction of cerebral activation.
In this two part webinar series, we will go the full circle of HD fNIRS: From practically setting up, conducting, and analyzing HD-fNIRS experiments using Dr. Boas' open source fNIRS analysis toolboxes AtlasViewer and Homer3 together with NIRx' NIRSport2 systems and Aurora/NIRSite software.
Part 1 covered experimental set up and data collection. Dr. Boas will explain how to design a HD optode array using AtlasViewer. Then we will address how to take those probes (.snirf) into NIRSITE and how to perform a straight-forward HD fNIRS measurement with the NIRSport2 system and Aurora.

In Part 2 Dr. Boas describes the analysis of the HD fNIRS data acquired with the NIRSport2 in Part 1. He will show how to do tomographic image reconstruction in AtlasViewer and trial-based signal analysis in Homer3.
See here for the data set from openfnirs.org to walk through the analysis of a HD-fNIRS finger tapping experiment.
