The effects of task context and brain injury on default mode network brain functional connectivity
INRODUCTION The default mode network (DMN) has been a major area of research in recent years. Studies have sought to determine the exact nature of its activity and how these profiles of neural activity respond to cognitive demands or are abnormal in pathological conditions [e.g. 1-3]. Activity within the network has been correlated with rest and anti-correlated with task performance [4]. As suc...
متن کاملEvaluation of Model-Based Methods in Estimating Dynamic Functional Connectivity of Brain Regions
Today, neuroscientists are interested in discovering human brain functions through brain networks. In this regard, the evaluation of dynamic changes in functional connectivity of the brain regions by using functional magnetic resonance imaging data has attracted their attention. In this paper, we focus on two model-based approaches, called the exponential weighted moving average model and the d...
متن کاملTinnitus Identification based on Brain Network Analysis of EEG Functional Connectivity
Introduction: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation of the brain...
متن کاملComputer-Aided Tinnitus Detection based on Brain Network Analysis of EEG Functional Connectivity
Background: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation and disruption of the brain net...
متن کاملTask-Related, Low-Frequency Task-Residual, and Resting State Activity in the Default Mode Network Brain Regions
The hypothesis of a default mode network (DMN) of brain function is based on observations of task-independent decreases of brain activity during effort as participants are engaged in tasks in contrast to resting. On the other hand, studies also showed that DMN regions activate rather than deactivate in response to task-related events. Thus, does DMN "deactivate" during effort as compared to res...
