Overcontrol in anorexia nervosa: Elevated prefrontal activity and amygdala connectivity in a working memory task with food distractors Open
View article: Acute tryptophan depletion balances altered resting-state functional connectivity of the salience network in female patients recovered from anorexia nervosa
Acute tryptophan depletion balances altered resting-state functional connectivity of the salience network in female patients recovered from anorexia nervosa Open
Background: It has been suggested that individuals predisposed to or recovered from anorexia nervosa experience a hyperserotonergic state associated with anxiety that might be mitigated by restricted food intake, because diminished levels …

No effects of acute tryptophan depletion on anxiety or mood in weight-recovered female patients with anorexia nervosa Open
View article: Metabolic state and value-based decision-making in acute and recovered female patients with anorexia nervosa
Metabolic state and value-based decision-making in acute and recovered female patients with anorexia nervosa Open
Background: Patients with anorexia nervosa forgo eating despite emaciation and severe health consequences. Such dysfunctional decision-making might be explained by an excessive level of self-control, alterations in homeostatic and hedonic …

Peptide YY3–36 concentration in acute- and long-term recovered anorexia nervosa Open
Purpose The gut–brain axis could be a possible key factor in the pathophysiology of anorexia nervosa. The neuropeptide peptide YY 3–36 , secreted by endocrine L cells of the gastrointestinal tract, is a known regulator of appetite and food…

Intact value-based decision-making during intertemporal choice in women with remitted anorexia nervosa? An fMRI study Open
Background: Extreme restrictive food choice in anorexia nervosa is thought to reflect excessive self-control and/or abnormal reward sensitivity. Studies using intertemporal choice paradigms have suggested an increased capacity to delay rew…

The real-life costs of emotion regulation in anorexia nervosa: a combined ecological momentary assessment and fMRI study Open
Regulation of emotions is necessary for successful attainment of short-term and long-term goals. However, over-regulation may also have its costs. In anorexia nervosa (AN), forgoing food intake despite emaciation and endocrine signals that…
View article: Processing and regulation of negative emotions in anorexia nervosa: An fMRI study
Processing and regulation of negative emotions in anorexia nervosa: An fMRI study Open
Theoretical models and recent advances in the treatment of anorexia nervosa (AN) have increasingly focused on the role of alterations in the processing and regulation of emotions. To date, however, our understanding of these changes is sti…

View article: Subliminal and supraliminal processing of reward-related stimuli in anorexia nervosa
Subliminal and supraliminal processing of reward-related stimuli in anorexia nervosa Open
Background Previous studies have highlighted the role of the brain reward and cognitive control systems in the etiology of anorexia nervosa (AN). In an attempt to disentangle the relative contribution of these systems to the disorder, we u…

View article: Partially restored resting-state functional connectivity in women recovered from anorexia nervosa
Partially restored resting-state functional connectivity in women recovered from anorexia nervosa Open
Background: We have previously shown increased resting-state functional connectivity (rsFC) in the frontoparietal network (FPN) and the default mode network (DMN) in patients with acute anorexia nervosa. Based on these findings we investig…

Preserved white matter microstructure in young patients with anorexia nervosa? Open
A massive but reversible reduction of cortical thickness and subcortical gray matter (GM) volumes in Anorexia Nervosa (AN) has been recently reported. However, the literature on alterations in white matter (WM) volume and microstructure ch…
View article: Abnormal functional global and local brain connectivity in female patients with anorexia nervosa
Abnormal functional global and local brain connectivity in female patients with anorexia nervosa Open
Background: Previous resting-state functional connectivity studies in patients with anorexia nervosa used independent component analysis or seed-based connectivity analysis to probe specific brain networks. Instead, modelling the entire br…
View article: Elevated cognitive control over reward processing in recovered female patients with anorexia nervosa
Elevated cognitive control over reward processing in recovered female patients with anorexia nervosa Open
Background: Individuals with anorexia nervosa are thought to exert excessive self-control to inhibit primary drives. Methods: This study used functional MRI (fMRI) to interrogate interactions between the neural correlates of cognitive cont…

Reduced functional connectivity in the thalamo‐insular subnetwork in patients with acute anorexia nervosa Open
The neural underpinnings of anorexia nervosa (AN) are poorly understood. Results from existing functional brain imaging studies using disorder‐relevant food‐ or body‐stimuli have been heterogeneous and may be biased due to varying complian…
View article: Temporal delay discounting in acutely ill and weight-recovered patients with anorexia nervosa
Temporal delay discounting in acutely ill and weight-recovered patients with anorexia nervosa Open
Background. Patients with anorexia nervosa (AN) are characterized by a very low body weight but readily give up immediate rewards (food) for long-term goals (slim figure), which might indicate an unusual level of self-control. This everyda…
