A Comparative Study of Brain Connectivity Visualization and Clustering Techniques
نویسندگان
چکیده
Present a novel approach of brain connectivity visualization of white matter pathways and gray matter areas using diffusion tensor imaging and functional magnetic resonance imaging. Clustering is an important tool for creating abstraction and filtration in general and is central representation in particular. While abstraction involves simplification and generalization, filtration here entails clustering. To visualization of brain volumetric using stream tube, stream surface, streamlines or variation of streamlines of nerve bundles of fibers pathways of brain. Different visualization techniques present here that is weighted graph comparison method, three dimensional neural maps represent in web-interface stand-alone approach similar to Google maps that shown with associated names, measurements and link outs of brain neural maps of different regions like corpus callosum, left cingulum and arcuate and a small portion of right arcuate, both cortico-spinal tracts and inferior frontooccipital fasciculi. Different clustering algorithm that is K-means, Spectral Clustering, Normalized Cut Expectation maximization and fuzzy c-means apply on nerve fiber cluster.

Functional Brain Connectivity Differences Between Different ADHD Presentations: Impaired Functional Segregation in ADHD-Combined Presentation but not in ADHD-Inattentive Presentation
Introduction: Contrary to Diagnostic and Statistical Manual of Mental Disorders (DSM-5), fifth edition, some studies indicate that ADHD-inattentive presentation (ADHD-I) is a distinct diagnostic disorder and not an ADHD presentation. Methods: In this study, 12 ADHD-combined presentation (ADHD-C), 10 ADHD-I, and 13 controls were enrolled and their resting state EEG recorded. Following thi...

Introduction: Many theories have been proposed about the etiology of autism. One is related to brain connectivity in patients with autism. Several studies have reported brain connectivity changes in autism disease. This study was performed on Electroencephalogram (EEG) studies that evaluated patients with autism, using functional brain connectivity, and compared them with typically-developing i...
متن کاملIdentification of mild cognitive impairment disease using brain functional connectivity and graph analysis in fMRI data
Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In th...
متن کاملClassification of Right/Left Hand Motor Imagery by Effective Connectivity Based on Transfer Entropy in EEG Signal
The right and left hand Motor Imagery (MI) analysis based on the electroencephalogram (EEG) signal can directly link the central nervous system to a computer or a device. This study aims to identify a set of robust and nonlinear effective brain connectivity features quantified by transfer entropy (TE) to characterize the relationship between brain regions from EEG signals and create a hierarchi...
