Resting-State Quantitative Electroencephalography Reveals Increased Neurophysiologic Connectivity in Depression
Symptoms of Major Depressive Disorder (MDD) are hypothesized to arise from dysfunction in brain networks linking the limbic system and cortical regions. Alterations in brain functional cortical connectivity in resting-state networks have been detected with functional imaging techniques, but neurophysiologic connectivity measures have not been systematically examined. We used weighted network an...
متن کاملWhole Brain Resting-State Analysis Reveals Decreased Functional Connectivity in Major Depression
Recently, both increases and decreases in resting-state functional connectivity have been found in major depression. However, these studies only assessed functional connectivity within a specific network or between a few regions of interest, while comorbidity and use of medication was not always controlled for. Therefore, the aim of the current study was to investigate whole-brain functional co...
متن کاملResting-state functional connectivity in major depression: abnormally increased contributions from subgenual cingulate cortex and thalamus.
BACKGROUND Positron emission tomography (PET) studies of major depression have revealed resting-state abnormalities in the prefrontal and cingulate cortices. Recently, fMRI has been adapted to examine connectivity within a specific resting-state neural network--the default-mode network--that includes medial prefrontal and anterior cingulate cortices. The goal of this study was to examine restin...
متن کاملResting-state functional MRI in depression unmasks increased connectivity between networks via the dorsal nexus.
To better understand intrinsic brain connections in major depression, we used a neuroimaging technique that measures resting state functional connectivity using functional MRI (fMRI). Three different brain networks--the cognitive control network, default mode network, and affective network--were investigated. Compared with controls, in depressed subjects each of these three networks had increas...
متن کاملAbnormal amygdala resting-state functional connectivity in adolescent depression.
IMPORTANCE Major depressive disorder (MDD) frequently emerges during adolescence and can lead to persistent illness, disability, and suicide. The maturational changes that take place in the brain during adolescence underscore the importance of examining neurobiological mechanisms during this time of early illness. However, neural mechanisms of depression in adolescents have been understudied. R...
