Toward a model-based cognitive neuroscience of mind wandering
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-03)
People often ‘‘mind wander” during everyday
tasks, temporarily losing track of time, place, or current task
goals. In laboratory-based tasks, mind wandering is often
associated with performance decrements in behavioral
variables and changes in neural recordings. Such empirical
associations provide descriptive accounts of mind
wandering – howit affects ongoing task performance – but fail
to ...
Predictors of Response to Web-Based Cognitive Behavioral Therapy With High-Intensity Face-to-Face Therapist Guidance for Depression: A Bayesian Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-06)
Background: Several studies have demonstrated the effect of guided Internet-based cognitive behavioral therapy (ICBT) for depression. However, ICBT is not suitable for all depressed patients and there is a considerable level of nonresponse. Research on predictors and moderators of outcome in ICBT is inconclusive.
Objective: This paper explored predictors of response to an intervention combining the ...

Intermittent Absence of Control during Reinforcement Learning Interferes with Pavlovian Bias in Action Selection
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-02)
The ability to control the occurrence of rewarding and punishing events is crucial for our well-being. Two ways to optimize performance are to follow heuristics like Pavlovian biases to approach reward and avoid loss or to rely more on slowly accumulated stimulus–action associations. Although reduced control over outcomes has been linked to suboptimal decision-making in clinical conditions associated ...
pypillometry: A Python package for pupillometric analyses
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-02)
The size of the human pupil is controlled by pairs of constrictor and dilator muscles that
allow its opening (dilation) and closing (constriction) in response to varying lighting conditions (Mathôt, 2018). Importantly, it has long been known that the pupil also reacts to
psychological important stimuli (Hess & Polt, 1960) and has been a firmly established tool for
studying “mental effort” in the ...
Weak rTMS-induced electric fields produce neural entrainment in humans
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-20)
Repetitive transcranial magnetic stimulation (rTMS) is a potent tool for modulating endogenous oscillations in humans. The current standard method for rTMS defines the stimulation intensity based on the evoked liminal response in the visual or motor system (e.g., resting motor threshold). The key limitation of the current approach is that the magnitude of the resulting electric field remains elusive. ...
Selecting stimulation intensity in repetitive transcranial magnetic stimulation studies: A systematic review between 1991 and 2020
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-22)
Repetitive transcranial magnetic stimulation (rTMS) is an increasingly used, non-invasive brain stimulation technique in neuroscience research and clinical practice with a broad spectrum of suggested applications. Among other parameters, the choice of stimulus intensity and intracranial electric field strength substantially impacts rTMS outcome. This review provides a systematic overview of the ...
Ө-γ Cross-Frequency Transcranial Alternating Current Stimulation over the Trough Impairs Cognitive Control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-06)
Cognitive control is a mental process, which underlies adaptive goal-directed decisions. Previous studies have linked cognitive control to electrophysiological fluctuations in the θ band and θ-γ cross-frequency coupling (CFC) arising from the cingulate and frontal cortices. However, to date, the behavioral consequences of different forms of θ-γ CFC remain elusive. Here, we studied the behavioral ...
Evidence for Cognitive Placebo and Nocebo Effects in Healthy Individuals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
Inactive interventions can have significant effects on cognitive performance. Understanding the generation of these cognitive placebo/nocebo effects is crucial for evaluating the cognitive impacts of interventional methods, such as non-invasive brain stimulation (NIBS). We report both cognitive placebo and nocebo effects on reward-based learning performance induced using an active sham NIBS protocol, ...
The interplay between executive control, behavioral variability and mind wandering: Insights from a high-definition transcranial direct-current stimulation study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-21)
While the involvement of executive processes in mind wandering is largely undebated, their exact relationship is subject to an ongoing debate and rarely studied dynamically within‐subject. Several brain‐stimulation studies using transcranial direct current stimulation (tDCS) have attempted to modulate mind‐wandering propensity by stimulating the left dorsolateral prefrontal cortex (DLPFC) which is ...
