Granger causality (GC) and dynamic causal modeling (DCM) are the two key approaches used to determine the directed interactions among brain areas. Recent discussions have provided a constructive account of the merits and demerits. GC, on one side, considers dependencies among measured responses, whereas DCM, on the other, models how neuronal activity in one brain area causes dynamics in another. In this study, our objective was to establish construct validity between GC and DCM in the context…

Construction of functional brain connectivity networks from fMRI data with driving and modulatory inputs: an extended conditional Granger causality approach

The findings suggest that the proposed scheme can be successfully used as a stand-alone or complementary to DCM approach to find directed causal connectivity patterns in task-related fMRI studies.

Transfer Entropy as a Measure of Brain Connectivity: A Critical Analysis With the Help of Neural Mass Models

Assessment of the capacity of bivariate Transfer Entropy to evaluate connectivity using data generated from simple neural mass models of connected Regions of Interest suggests that TE can reliably estimate the strength of connectivity if neural populations work in their linear regions, and if the epoch lengths are longer than 10 s.

Converging Resting State Networks Unravels Potential Remote Effects of Transcranial Magnetic Stimulation for Major Depression

Investigation of resting-state fMRI data of 100 healthy subjects by exploring three overlapping functional networks associated with the psychopathologically MDD-related areas identified potential targets for brain stimulation treatment and contributed to the optimization of patient-specific brain stimulation protocols.

Altered Directed Functional Connectivity of the Hippocampus in Mild Cognitive Impairment and Alzheimer’s Disease: A Resting-State fMRI Study

The hippocampus is generally reported as one of the regions most impacted by Alzheimer’s disease (AD) and is closely associated with memory function and orientation. Undirected functional

Beyond the disconnectivity hypothesis of schizophrenia.

This investigation goes beyond the disconnectivity hypothesis by drawing attention to differences in schizophrenia between backprojections and forward connections, with the backward connections from the precuneus and PCC implicated in memory stronger in schizophrenia.

Effective connectivity in autism

M measuring in the first large‐scale study differences in effective, that is directed, connectivity between brain areas in autism compared to controls found that in autism, the middle temporal gyrus and other temporal areas had lower effective connectivities to the precuneus and cuneus.

Alterations in the default mode-salience network circuit provide a potential mechanism supporting negativity bias in depression.

Findings indicate that greater network activation and, specifically, influence of DMN on SAL, support negativity bias among previously depressed individuals.

A resting state fMRI analysis pipeline for pooling inference across diverse cohorts: an ENIGMA rs-fMRI protocol

This work proposes an initial pipeline for multi-site rsfMRI analysis to allow research groups around the world to analyze scans in a harmonized way, and to perform coordinated statistical tests.

Is Granger Causality a Viable Technique for Analyzing fMRI Data?

The results suggest that Granger causality is a viable technique for analyzing fMRI data when the questions are appropriately formulated and can be reliably detected as a positive correlation when realistic fMRI temporal resolution and noise level were used.
