Aberrant uncertainty processing is linked to psychotic-like experiences, autistic traits, and is reflected in pupil dilation during probabilistic learning
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-28)Aberrant belief updating due to misestimation of uncertainty and an increased perception of the world as volatile (i.e., unstable) has been found in autism and psychotic disorders. Pupil dilation tracks events that warrant belief updating, likely refecting the adjustment of neural gain. However, whether subclinical autistic or psychotic symptoms afect this adjustment and how they relate to learning ... -

The antidepressant effect of intermittent theta burst stimulation (iTBS): study protocol for a randomized double-blind sham-controlled trial
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-02)Background Intermittent theta burst stimulation (iTBS) when applied over the left dorsolateral prefrontal cortex (DLPFC) has been shown to be equally effective and safe to treat depression compared to traditional repetitive transcranial magnetic stimulation (rTMS) paradigms. This protocol describes a funded single-centre, double-blind, randomized placebo-controlled, clinical trial to investigate ... -
Echoes from Intrinsic Connectivity Networks in the Subcortex
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-27)Decades of research have greatly improved our understanding of intrinsic human brain organization in terms of functional networks and the transmodal hubs within the cortex at which they converge. However, substrates of multinetwork integration in the human subcortex are relatively uncharted. Here, we leveraged recent advances in subcortical atlasing and ultra-high field (7 T) imaging optimized for ... -

Modulation of mind wandering using transcranial direct current stimulation: A meta-analysis based on electric field modeling
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-23)Mind wandering (MW) is a heterogeneous construct involving task-unrelated thoughts. Recently, the interest in modulating MW propensity via non-invasive brain stimulation techniques has increased. Single-session transcranial direct current stimulation (tDCS) in healthy controls has led to mixed results in modulating MW propensity, possibly due to methodological heterogeneity. Therefore, our aim was ... -
Tracking the current in the Alzheimer's brain - Systematic differences between patients and healthy controls in the electric field induced by tDCS
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-26)Background: Several studies on patients with Alzheimer’s disease (AD) have used transcranial direct current stimulation (tDCS) to enhance neural excitability in the left dorsolateral prefrontal cortex (lDLPFC). Interindividual differences in brain anatomy in AD patients pose a challenge to efficiently target the lDLPFC using scalpbased coordinates, calling for new and more precise tDCS protocols. ... -
Transcranial direct-current stimulation enhances Pavlovian tendencies during intermittent loss of control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-09)Introduction: Pavlovian bias is an innate motivational tendency to approach rewards and remain passive in the face of punishment. The relative reliance on Pavlovian valuation has been found to increase when the perceived control over environmental reinforcers is compromised, leading to behavior resembling learned helplessness (LH).<p> <p>Methods: Sixty healthy young adults underwent a Go-NoGo ...
