Effects of transcranial direct current stimulation for treating depression: A modeling study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-28)
<p><i>Background</i>:
Transcranial direct current stimulation (tDCS) above the left dorsolateral prefrontal cortex (lDLPFC) has been widely used to improve symptoms of major depressive disorder (MDD). However, the effects of different stimulation protocols in the entire frontal lobe have not been investigated in a large sample including patient data.</p>
<p><i>Methods</i>:
We used 38 head ...
Data from ‘Placebo Enhances Reward Learning in Healthy Individuals’
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-20)
This dataset contains three repeated measures of a standard reward-based reinforcement-learning task from 29 healthy male individuals who participated in three experimental sessions exploring cognitive placebo effects on reward learning. The dataset includes behavioural data (accuracy, reaction times) during learning and transfer, estimates of model-free computational analysis, self-reported arousal ...
Skiing and thinking about it: Moment-to-moment and retrospective analysis of emotions in an extreme sport
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-20)
Happiness is typically reported as an important reason for participating in challenging
activities like extreme sport. While in the middle of the activity, however, participants
do not seem particularly happy. So where does the happiness come from? The
article proposes some answers from a study of facially expressed emotions measured
moment-by-moment during a backcountry skiing event. Self-reported ...
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, ...
Head models of healthy and depressed adults for simulating the electric fields of non-invasive electric brain stimulation [version 2; referees: 2 approved]
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-06)
During the past decade, it became clear that the electric field elicited by non-invasive brain stimulation (NIBS) techniques such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) are substantially influenced by variations in individual head and brain anatomy. In addition to structural variations in the healthy, several psychiatric disorders are characterized ...
