Strong evidence implicates prefrontal cortex (PFC) as a major source of functional impairment in severe mental illness such as schizophrenia. Numerous schizophrenia studies report deficits in PFC structure, activation, and functional connectivity in patients with chronic illness, suggesting that deficient PFC functional connectivity occurs in this disorder. However, the PFC functional connectiv...

Attention Deficit Hyperactive Disorder (ADHD) is one of the most common disorders affecting young children, and its underlying mechanism is not completely understood. This paper proposes a phenotypic integrated machine learning framework to investigate functional connectivity alterations between ADHD and control subjects not diagnosed with ADHD, employing fMRI data. Our aim is to apply computat...

This study employed graph theory and machine learning analysis of multiparametric MRI data to improve characterization and prediction in autism spectrum disorders (ASD). Data from 127 children with ASD (13.5±6.0 years) and 153 age- and gender-matched typically developing children (14.5±5.7 years) were selected from the multi-center Functional Connectome Project. Regional gray matter volume and ...

In recent years, the brain's "default network," a set of regions characterized by decreased neural activity during goal-oriented tasks, has generated a significant amount of interest, as well as controversy. Much of the discussion has focused on the relationship of these regions to a "default mode" of brain function. In early studies, investigators suggested that, the brain's default mode suppo...

The importance of connectivity is well established in traditional disciplinary environmental fields, namely hydrology and ecology. Although conventions for defining connectivity in those fields differ, structural connectivity typically refers to the degree of spatial connectedness of landscape features, whereas functional connectivity refers to the degree of permeability of landscapes for certa...

To investigate the additional value of EEG functional connectivity features, in addition to non-coupling for outcome prediction comatose patients after cardiac arrest. Prospective, multicenter cohort study. Coherence, phase locking value, and mutual information were calculated 19-channel EEGs at 12 h, 24 h 48 Three sets machine learning classification models trained validated with connectivity,...

Functional network connectivity (FNC) is a method of analyzing the temporal relationship of anatomical brain components, comparing the synchronicity between patient groups or conditions. We use functional-connectivity measures between independent components to classify between Schizophrenia patients and healthy controls during resting-state. Connectivity is measured using a variety of graph-the...

Introduction: Osteoarthritis of the knee is the most prevalent type of arthritis that causes persistent pain and reduces the quality of life. However, no treatment alleviates symptoms or stops the disease from progressing. Functional magnetic resonance imaging (fMRI) studies can provide information on neural mechanisms of pain by assessing correlation patterns among the different regions of the...

Brain development is adversely affected by preterm birth. Magnetic resonance image analysis has revealed a complex fusion of structural alterations across all tissue compartments that are apparent by term-equivalent age, persistent into adolescence and adulthood, and associated with wide-ranging neurodevelopment disorders. Although functional MRI has revealed the relatively advanced organisatio...
