Directionality of large-scale resting-state brain networks during eyes open and eyes closed conditions
The present study examined directional connections in the brain among resting-state networks (RSNs) when the participant had their eyes open (EO) or had their eyes closed (EC). The resting-state fMRI data were collected from 20 healthy participants (9 males, 20.17 ± 2.74 years) under the EO and EC states. Independent component analysis (ICA) was applied to identify the separated RSNs (i.e., the...
متن کاملAmplitude differences in high-frequency fMRI signals between eyes open and eyes closed resting states
Recent studies employing rapid sampling techniques have demonstrated that the resting state fMRI (rs-fMRI) signal exhibits synchronized activities at frequencies much higher than the conventional frequency range (<0.1 Hz). However, little work has investigated the changes in the high-frequency fluctuations between different resting states. Here, we acquired rs-fMRI data at a high sampling rate ...
متن کاملDetecting Static and Dynamic Differences between Eyes-Closed and Eyes-Open Resting States Using ASL and BOLD fMRI
Resting-state fMRI studies have increasingly focused on multi-contrast techniques, such as BOLD and ASL imaging. However, these techniques may reveal different aspects of brain activity (e.g., static vs. dynamic), and little is known about the similarity or disparity of these techniques in detecting resting-state brain activity. It is therefore important to assess the static and dynamic charact...
متن کاملmodified schirmer's test in normal eyes: open versus closed eyes and 1-minute versus 5-minute tests
purpose : to assess the results of 1-minute and 5-minute schirmer's test (st) when the eyes are open (sto) and closed (stc) in normal participants. methods : in a comparative, observational case series study, 34 normal volunteers were included in the study. inclusion criteria were normal ophthalmologic findings except for refractive errors, no use of contact lenses, no history of previous ...
متن کاملThe Difference of Brain Functional Connectivity between Eyes-Closed and Eyes-Open Using Graph Theoretical Analysis
To study the differences in functional brain networks between eyes-closed (EC) and eyes-open (EO) at resting state, electroencephalographic (EEG) activity was recorded in 21 normal adults during EC and EO states. The synchronization likelihood (SL) was applied to measure correlations between all pairwise EEG channels, and then the SL matrices were converted to graphs by thresholding. Graphs wer...
