Interrater and intermethod reliability of default mode network selection

Brain's Default Mode Network

Emotional faces and the default mode network.

The default-mode network (DMN) of the human brain has become a central topic of cognitive neuroscience research. Although alterations in its resting state activity and in its recruitment during tasks have been reported for several mental and neurodegenerative disorders, its role in emotion processing has received relatively little attention. We investigated brain responses to different categori...

Interrater Reliability of Pupillary Assessments.

BACKGROUND Subjective scoring of pupil reactivity is a fundamental element of the neurological examination for which the pupillometer provides an objective measure. METHODS This single-blinded observational study examined interrater reliability of pupil exam findings between two practitioners and between practitioners and a pupillometer. RESULTS From 2329 paired assessments, the interrater ...

Default Mode Network Connectivity in Stroke Patients

The pathophysiology of episodic memory dysfunction after infarction is not completely understood. It has been suggested that infarctions located anywhere in the brain can induce widespread effects causing disruption of functional networks of the cortical regions. The default mode network, which includes the medial temporal lobe, is a functional network that is associated with episodic memory pr...

The Default Mode Network in Autism.

Autism spectrum disorder (ASD) is characterized by deficits in social communication and interaction. Since its discovery as a major functional brain system, the default mode network (DMN) has been implicated in a number of psychiatric disorders, including ASD. Here we review converging multimodal evidence for DMN dysfunction in the context of specific components of social cognitive dysfunction ...
