Dynamic up- and down-regulation of thedefault (DMN) and extrinsic (EMN) modenetworks during alternating task-on and task-offperiods
Hugdahl, Kenneth; Kazimierczak, Katarzyna Anna; Beresniewicz, Justyna; Kompus, Kristiina; Westerhausen, René; Ersland, Lars; Grüner, Renate; Specht, Karsten (Peer reviewed; Journal article, 2019)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 ... -
GABA, glutamatergic dynamics and BOLD contrast assessed concurrently using functional MRS during a cognitive task
Craven, Alexander R.; Dwyer, Gerard Eric; Ersland, Lars; Kazimierczak, Katarzyna Anna; Noeske, Ralph; Sandøy, Lydia Brunvoll; Johnsen, Erik; Hugdahl, Kenneth Jan (Journal article; Peer reviewed, 2023)A recurring issue in functional neuroimaging is how to link task-driven haemodynamic blood oxygen level dependent functional MRI (BOLD-fMRI) responses to underlying neurochemistry at the synaptic level. Glutamate and ... -
Similarities and differences between intermittent and continuous resting-state fMRI
Beresniewicz, Justyna; Riemer, Frank; Kazimierczak, Katarzyna Anna; Ersland, Lars; Craven, Alexander R.; Hugdahl, Kenneth Jan; Grüner, Renate (Journal article; Peer reviewed, 2023)Introduction: Functional Magnetic Resonance Imaging (fMRI) block-design experiments typically include active ON-blocks with presentation of cognitive tasks which are contrasted with OFF- blocks with no tasks presented. ... -
Simultaneous Measurement of the BOLD Effect and Metabolic Changes in Response to Visual Stimulation Using the MEGA-PRESS Sequence at 3 T
Dwyer, Gerard Eric; Craven, Alexander R.; Beresniewicz, Justyna; Kazimierczak, Katarzyna Anna; Ersland, Lars; Hugdahl, Kenneth Jan; Grüner, Eli Renate (Journal article; Peer reviewed, 2021)The blood oxygen level dependent (BOLD) effect that provides the contrast in functional magnetic resonance imaging (fMRI) has been demonstrated to affect the linewidth of spectral peaks as measured with magnetic resonance ...
