  author={Marco Antonio Pinto-Orellana and Hugo Lewi Hammer},
Graph network analysis (GNA) showed a remarkable role for understanding brain functions, but its application is mainly narrowed to fMRI research. Connectivity analysis (CA) is introduced as a signal-to-graph mapping in a time-causality framework. In this paper, we investigate the application of GNA/CA in fNIRS. To solve the inherent challenges of using CA, we also propose a novel metric: a maximum cross-lag magnitude (MCLM) that efficiently extracts major causality information. We tested MCLM…

Effective Connectivity Analysis of the Brain Network in Drivers during Actual Driving Using Near-Infrared Spectroscopy

Findings indicate that the hemodynamic activity level of the cerebral cortex increases linearly with increasing cognitive workload, which can be strengthened by a Cognitive workload, but also can be weakened by a superfluous cognitive workload.

Application of Graph Theory for Identifying Connectivity Patterns in Human Brain Networks: A Systematic Review

A systematic review of the existing functional and effective connectivity methods used to construct the brain network, along with their advantages and pitfalls, to provide insight into how to utilize graph theoretical measures to make neurobiological inferences regarding the mechanisms underlying human cognition and behavior as well as different brain disorders.

Deep Neural Networks for Assessing Functional Connectivity: an fNIRS Study

It is emphasized that ANN can be used as an appropriate method to estimate the temporal relation among brain networks during resting-state as it provides valuable insight into the intrinsic networks of the human brain.

Analysis of speech imagery using brain connectivity estimators

Coherence, an EEG synchronicity parameter is calculated to quantitatively analyze the concurrence of the different regions of the brain while performing speech imagery and the observations suggest that the proposed methodology is a promising non-invasive approach to study directional connectivity in the brain.

Effective Connectivity of Cortical Sensorimotor Networks During Finger Movement Tasks: A Simultaneous fNIRS, fMRI, EEG Study

This simultaneous fMRI, fNIRS and EEG study has shown through independent GC analysis of the respective time series that a bi-directional effective connectivity occurs within a cortico-cortical sensorimotor network (SMC, PMC and DLPFC) during finger movement tasks.

Current Status and Issues Regarding Pre-processing of fNIRS Neuroimaging Data: An Investigation of Diverse Signal Filtering Methods Within a General Linear Model Framework

To review and investigate which information is generally included in published fNIRS papers, and to define a signal pre-processing procedure to set a common ground for standardization guidelines, a simulation analysis with synthetic fNirS data is performed to optimize the signal filtering step before applying the GLM method for statistical inference.

The NIRS Brain AnalyzIR Toolbox

The NIRS Brain AnalyzIR toolbox is introduced as an open-source Matlab-based analysis package for fNIRS data management, pre-processing, and first- and second-level statistical analysis, based on the object-oriented programming paradigm.

Simultaneous acquisition of EEG and NIRS during cognitive tasks for an open access dataset

An open access multimodal brain-imaging dataset of simultaneous electroencephalography (EEG) and near-infrared spectroscopy (NIRS) recordings is provided to facilitate performance evaluation and comparison of many neuroimaging analysis techniques.
