Correlation between Traits of Emotion-Based Impulsivity and Intrinsic Default-Mode Network Activity

Correlation between Traits of Emotion-Based Impulsivity and Intrinsic Default-Mode Network Activity

Negative urgency (NU) and positive urgency (PU) are implicated in several high-risk behaviors, such as eating disorders, substance use disorders, and nonsuicidal self-injury behavior. The current study aimed to explore the possible link between trait of urgency and brain activity at rest. We assessed the amplitude of low-frequency fluctuations (ALFF) of the resting-state functional magnetic res...

Study on the Relationships between Intrinsic Functional Connectivity of the Default Mode Network and Transient Epileptic Activity

RATIONALE Simultaneous recording of electroencephalogram and functional MRI (EEG-fMRI) is a powerful tool for localizing epileptic networks via the detection of hemodynamic changes correlated with interictal epileptic discharges (IEDs). fMRI can be used to study the long-lasting effect of epileptic activity by assessing stationary functional connectivity during the resting-state period [especia...

Brain's Default Mode Network

Association between abnormal default mode network activity and suicidality in depressed adolescents

BACKGROUND Suicide is the second leading cause of death among 15- to 29-year-olds in China, and 60 % of suicidal patients have a history of depression. Previous brain imaging studies have shown that depression and suicide may be associated with abnormal activity in default mode network (DMN) regions. However, no study has specifically investigated the relationship between DMN functional activit...

Default Mode Network (DMN) Activity during Olfactory Processing

Introduction: The dynamics of resting state networks during active and passive task performance has received increased attention in recent times [1, 2]. Several studies have reported modulations in the default mode network (DMN) (or deactivations) during the performance of sensoryand cognitivefMRI tasks [1, 2, 3]. However, no study has investigated such modulations in relation to olfaction. Usi...
