Dynamic up- and down-regulation of the default (DMN) and extrinsic (EMN) mode networks during alternating task-on and task-off periods
Hugdahl, Kenneth; Kazimierczak, Katarzyna Anna; Beresniewicz, Justyna; Kompus, Kristiina; Westerhausen, René; Ersland, Lars; Grüner, Renate; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-19)Using fMRI, Hugdahl et al. (2015) reported the existence of a general-domain cortical network during active task-processing which was non-specific to the cognitive task being processed. They labelled this network the extrinsic mode network (EMN). The EMN would be predicted to be negatively, or anti-correlated with the classic default mode network (DMN), typically observed during periods of rest, ... -
Effects of motion correction, sampling rate and parametric modelling in dynamic contrast enhanced MRI of the temporomandibular joint in children affected with juvenile idiopathic arthritis
Starck, Lea; Andersen, Erling; Macíček, Ondřej; Angenete, Oskar W; Augdal, Thomas Angell; Rosendahl, Karen; Jirík, Radovan; Grüner, Renate (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-13)The temporomandibular joint (TMJ) is typically involved in 45–87% of children with Juvenile Idiopathic Arthritis (JIA). Accurate diagnosis of JIA is difficult as various clinical tests, including MRI, disagree. The purpose of this study is to optimize the methodological aspects of Dynamic Contrast Enhanced (DCE) MRI of the TMJ in children. In this cross-sectional study, including data from 73 JIA ...
