Inhibitory control and error processing in Obsessive-Compulsive Disorder: A mega-analysis of task-based fMRI data by the ENIGMA-OCD consortium

Nadža Džinalija, Odile A. van den Heuvel, Helen Blair Simpson, Iliyan Ivanov, Ana Isabel Araújo, Srinivas Balachander, Jan Carl Beucke, Daniel Brandeis, Silvia Brem, Willem B. Bruin, Jan K. Buitelaar, Miguel S. Castelo-Branco, 최선아, Goi Khia Eng, Sophie Fitzsimmons, , Ilya Milos Veer

This study analyzes fMRI data from OCD patients and controls to identify age-specific differences in brain activation during inhibitory control and error processing.

Executive control in Obsessive-Compulsive Disorder: A worldwide mega-analysis of task-based functional neuroimaging data of the ENIGMA-OCD consortium

Nadža Džinalija, Ilya Milos Veer, Helen Blair Simpson, Iliyan Ivanov, Srinivas Balachander, Francesco Benedetti, Federico Calesella, Sophie Fitzsimmons, Rosa Grützmann, Kristen Hagen, Bjarne K. A. Hansen, Stephan Heinzel, Chaim Huyser, Jonathan Ipser, Fern Jaspers‐Fayer, , Chris Vriend

This study analyzes fMRI data from OCD patients and controls to identify neural activation patterns during executive control tasks, finding reduced activation in frontoparietal regions and increased default mode network activity in OCD.

Neuronal morphology and physiology, functional brain networks and memory in temporal lobe epilepsy

Linda Douw, Ida A. Nissen, Sophie Fitzsimmons, Fernando A. N. Santos, Arjan Hillebrand, Elisabeth C.W. van Straaten, Cornelis Jan Stam, Philip C. De Witt Hamer, Johannes C. Baayen, Martin Klein, Jaap C. Reijneveld, Djai B. Heyer, Matthijs B Verhoog, René Wilbers, Sarah Hunt, , Natalia A. Goriounova

The paper links functional network integration in the default mode network to cellular properties in TLE patients, showing correlations between network centrality and memory performance.

Resting-state and task-based centrality of dorsolateral prefrontal cortex predict resilience to inhibitory repetitive transcranial magnetic stimulation

Sophie Fitzsimmons, Linda Douw, Odile A. van den Heuvel, Ysbrand D. van der Werf, Chris Vriend

The paper investigates how baseline functional network properties of the dorsolateral prefrontal cortex predict resilience to inhibitory rTMS, finding that globally integrated regions show greater resilience.
