Associations Between Resting State Functional Connectivity and Trajectories of General Psychopathology in Emerging Adolescents
… symptoms and is associated with alterations in resting state functional connectivity (RSFC). Specifically, aberrant connectivity within and between networks responsible for higher-order cognition and attention has been concurrently related to higher levels of p-factor scores in youth. It remains …

Cortical Cartography: Mapping Functional Areas Across the Human Brain with Resting State Functional Connectivity MRI
… systems of multiple interconnected “functional areas”. Each functional area possesses a unique combination of inputs, outputs, and internal structure, and is thought to make a distinct contribution to information processing. Thus, the study of each area's normal function, …

Factors Affecting Resting-State Functional Connectivity Across Three Intrinsically Connected Networks in Traumatic Brain Injury
… investigated the factors that influence post-TBI functional connectivity within three intrinsically connected networks; the default mode network (DMN), central executive network (CEN), and salience network (SN). The aim was to develop a predictive model for each network, based off a combination of …

SHARED AND UNIQUE PATTERNS OF RESTING-STATE FUNCTIONAL CONNECTIVITY LINKED TO ATTENTIONAL AND INTERPRETATION BIASES
… to form a grammatically correct and meaningful statement using five of the six words as quickly as possible. Moreover, to investigate the neural mechanism of cognitive bias, resting-state functional MRI data were collected. Results showed that each of the cognitive biases has its own pattern of …

Novel Functional Magnetic Resonance Imaging Analysis Approaches for Investigations of the Dynamics of Resting-State Functional Connectivity
… of blood-oxygenation level-dependent functional magnetic resonance imaging (BOLD fMRI) signals are highly synchronous between brain regions that serve similar functions. This provides a means to investigate functional networks of the human brain; however, most data analysis techniques …

RESTING-STATE FUNCTIONAL CONNECTIVITY CORRELATES OF ATTENTIONAL BIAS IN AN EMOTIONAL FREE VIEWING PARADIGM: AN EYE-TRACKING INVESTIGATION
… free viewing task, this study set to clarify resting-state network contributions from three large scale brain networks: frontoparietal, default mode, and salience networks. Results indicate participants displayed significant biases to negative/threat stimuli, and these attentional biases …

Resting-State Functional Connectivity in Veterans with Post-Traumatic Stress Disorder and Combat-Exposed Control Veterans: A Graph Theory Based Network Analysis
… study is the first to our knowledge to examine resting-state functional connectivity within default-mode, salience, and central executive networks in an all-male sample of combat veterans with post-traumatic stress disorder (PTSD) and combat-exposed Control veterans. Prior studies of …

Neuroimaging Depression Risk in a Sample of Never-Depressed Children
… in children’s neural structure, function, and functional connectivity, most have used samples that include participants with a personal history of depression or older samples (i.e., past the typical age of onset for depressive disorders). These approaches limit what can be determined regarding …

A neuroimaging study to characterise adolescent major depressive disorder, the effects of cognitive behavioural therapy, and potential subtypes based on familial loading
… in cortical thickness, white matter volume, and resting-state functional connectivity, using the largest studied sample of adolescent MDD patients under the age of 18 years. This thesis further aimed to investigate CBT’s effects on brain function, and whether adolescent MDD patients could be …

Concussion Recovery and Skilled Performance in Working-Aged Adults: Sex Differences in the Neural Correlates of Persisting Symptoms After Concussion
… dizziness, cortical volumes and thickness, and resting-state functional connectivity (RSFC) were assessed. Females demonstrated slower CMI task performance, reduced cortical volume (left cuneus and superior frontal), thinner cortex (left precuneus), greater RPQ-3 symptom severity, and lower RSFC …
