Decreased regional homogeneity in schizophrenia: a resting state functional magnetic resonance imaging study.
We used a newly reported regional homogeneity approach to measure the temporal homogeneity of blood oxygen level-dependent signal for exploring the brain activity of schizophrenia in a resting state. The results showed decreased regional homogeneity in schizophrenia, which distributed over the bilateral frontal, temporal, occipital, cerebellar posterior, right parietal and left limbic lobes, si...
متن کاملRegional homogeneity changes in early and advanced Parkinson’s disease: a resting state functional magnetic resonance imaging study
Objective: Previous work has shown regional homogeneity (ReHo) differences in Parkinson’s disease (PD) patients. So looking in more detail at differences between early and late stages is valuable. The aim of our study was to investigate brain activity of early and advanced PD in the resting state by using a ReHo approach. Methods: Functional magnetic resonance images were acquired in 35 patient...
متن کاملRegional Homogeneity
Much effort has been made to understand the organizational principles of human brain function using functional magnetic resonance imaging (fMRI) methods, among which resting-state fMRI (rfMRI) is an increasingly recognized technique for measuring the intrinsic dynamics of the human brain. Functional connectivity (FC) with rfMRI is the most widely used method to describe remote or long-distance ...
متن کاملRegional Homogeneity within the Default Mode Network in Bipolar Depression: A Resting-State Functional Magnetic Resonance Imaging Study
AIM We sought to use a regional homogeneity (ReHo) approach as an index in resting-state functional magnetic resonance imaging (fMRI) to investigate the features of spontaneous brain activity within the default mode network (DMN) in patients suffering from bipolar depression (BD). METHODS Twenty-six patients with BD and 26 gender-, age-, and education-matched healthy subjects participated in ...
متن کاملRegional homogeneity of resting-state fMRI contributes to both neurovascular and task activation variations.
The task induced blood oxygenation level dependent signal changes observed using functional magnetic resonance imaging (fMRI) are critically dependent on the relationship between neuronal activity and hemodynamic response. Therefore, understanding the nature of neurovascular coupling is important when interpreting fMRI signal changes evoked via task. In this study, we used regional homogeneity ...
