The relation of hippocampal subfield volumes to verbal episodic memory measured by the California Verbal Learning Test II in healthy adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-08)
Total hippocampal volume has previously been shown to correlate with performance on tests for verbal episodic memory. However, there are sparse evidence on how hippocampal subfield volumes are related to verbal episodic memory in healthy adults. The present study investigated the association between volumes of separate hippocampal subfields and verbal episodic memory performance in healthy volunteers. ...
The Opioid Receptor Mu 1 (OPRM1) rs1799971 and Catechol-O-methyltransferase (COMT) rs4680 as genetic markers for placebo analgesia
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-16)
The placebo effect is considered the core example of mind-body interactions. However, individual differences produce large placebo response variability in both healthy volunteers and patients. The placebo response in pain, placebo analgesia, may be dependent on both the opioid system and the dopaminergic system. Previous studies suggest that genetic variability affects the function of these 2 systems. ...
Failure to Find a Conditioned Placebo Analgesic Response
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-30)
<p><i>Background</i>: Associative learning has, in several studies, been modulated by the sex of the participant. Consistent with this, a recent review found that conditioned nocebo effects are stronger in females than in males.</p> <p><i>Purpose</i>: It has been suggested that conditioned placebo responses are stronger in females, and this hypothesis was investigated in the present study. Cortisol ...
Hippocampal Subfields in Adolescent Anorexia Nervosa
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-25)
Patients with anorexia nervosa (AN) exhibit volume reduction in cerebral gray matter (GM), and several studies report reduced hippocampus volume. The hippocampal subfields (HS) are functionally and structurally distinct, and appear to respond differently to neuropathology. The aim of this study was to investigate HS volumes in adolescent females with restrictive AN compared to a healthy age-matched ...
Commentary: Transcranial stimulation of the frontal lobes increases propensity of mind-wandering without changing meta-awareness

Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 min in young healthy adults
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...
Blame it on the weather? The association between pain in fibromyalgia, relative humidity, temperature and barometric pressure
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-10)
Self-reported pain levels in patients with fibromyalgia may change according to weather conditions. Previous studies suggest that low barometric pressure (BMP) is significantly related to increased pain, but that the contribution of changes in BMP has limited clinical relevance. The present study examined whether BMP influenced variability in perceived stress, and if stress levels moderated or ...
