Research Article The Difference of Brain Functional Connectivity between Eyes-Closed and Eyes-Open Using Graph Theoretical Analysis

by Bo Tan, Xianxian Kong, Ping Yang, Zhenlan Jin, Ling Li
"... permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. To study the differences in functional brain networks between eyes-closed (EC) and eyes-open (EO) at resting state, electro-encephalographic (EEG) activity was recorded in 21 normal ..."

Eye closure in darkness animates sensory systems

by Esther Marx, Thomas Stephan, Annina Nolte, Angela Deutschländer, Klaus C. Seelos, Marianne Dieterich, Thomas Brandt , 2003
"... Single subject and group analyses (n = 12) showed that the eyes-open and eyes-closed states in complete darkness considerably and consistently differ in the patterns of associated brain activation in fMRI. During nonchanging external stimulation, ocular motor and attentional systems were activated w ..."

RESEARCH ARTICLE Investigating the Temporal Patterns within and between Intrinsic Connectivity Networks under Eyes-Open and Eyes-Closed Resting States: A Dynamical Functional Connectivity Study Based on Phase Synchronization

by Lihua Li, Tao Xu, Zhongxiang Ding
"... The brain active patterns were organized differently under resting states of eyes open (EO) and eyes closed (EC). The altered voxel-wise and regional-wise resting state active pat-terns under EO/EC were found by static analysis. More importantly, dynamical spontaneous functional connectivity has bee ..."

by Hyperactivity Disorder , 2014
"... Objective: Quantitative electroencephalography (qEEG) has been increasingly used to evaluate patients with attention deficit hyperactivity disorder (ADHD). The aim of this study was to assess the correlation between qEEG data and symptom severity in patients with ADHD. Methods: Fifteen patients with ..."

with ADHD and 20 healthy controls (HCs) were recruited. Electroencephalography was assessed in the resting-state, and qEEG data were obtained in the eyes-closed state. The Korean version of the ADHD Rating Scale (K-ARS) and continuous performance tests (CPTs) were used to assess all participants. Results

Functional Brain Imaging Unit, Souraski Medical Center

by Ilana Podlipski, Eti Ben Simon, Talma Hendler, Nathan Intrator
"... The need to infer brain states in a data driven approach is crucial for BCI applications as well as for neuroscience research. In this work we present a novel classification framework based on Regularized Linear Regression classifier constructed from time-frequency decomposition of an EEG (Electro-E ..."

Furthermore, our findings reveal interesting patterns of relations between experimental conditions, EEG frequencies, regularization parameters and classifier choice. This viable tool enables

Resting-State Network Disruption and APOE Genotype in Alzheimer’s Disease: A lagged Functional Connectivity Study

by Leonides Canuet, Ivan Tellado, Veronica Couceiro, Carmen Fraile, Lucia Fern, Ryouhei Ishii Masatoshi Takeda
"... Background: The apolipoprotein E epsilon 4 (APOE-4) is associated with a genetic vulnerability to Alzheimer’s disease (AD) and with AD-related abnormalities in cortical rhythms. However, it is unclear whether APOE-4 is linked to a specific pattern of intrinsic functional disintegration of the brain ..."

’’. Methodology/Principal Findings: Resting EEG was recorded during awake, eyes-closed state in 125 patients with AD and 60 elderly controls. Source current density and functional connectivity were determined using eLORETA. Patients with AD exhibited reduced parieto-occipital alpha oscillations compared

Schizophrenia Startle Reaction

by Kemal Arikan, Nash N. Boutros, Erol Bozhuyuk, B. Cagri Poyraz, Mert Savrun, Reha Bayar, Aysegul Gunduz, Feray Karaali-savrun, Mehmet Yaman, Major Depressive Disorder
"... Previous studies have shown alterations of eyeblink reflex in patients with various psychiatric disorders. It has previously been demonstrated by our group that EEG measures of the reactivity to eye opening could effectively predict patient-reported startle response in patients with acute stress rea ..."

Automatic Eye State Recognition and Closed-eye Photo Correction

by Zhaojie Liu, Haizhou Ai
"... In this paper, we present an approach for eye state recognition and closed-eye photo correction. For eye state recognition, AdaBoosted cascade open-eye detectors of different scales are trained. For closedeye photo correction, a PCA generative model of concatenated corresponding closed-eye and open- ..."
