Cognitive and MRI trajectories for prediction of Alzheimer’s disease
(Journal article; Peer reviewed, 2021)The concept of Mild Cognitive Impairment (MCI) is used to describe the early stages of Alzheimer’s disease (AD), and identification and treatment before further decline is an important clinical task. We selected longitudinal ... -
Cognitive function and brain plasticity in a rat model of shift work: role of daily rhythms, sleep and glucocorticoids
(Journal article; Peer reviewed, 2020)Many occupations require operations during the night-time when the internal circadian clock promotes sleep, in many cases resulting in impairments in cognitive performance and brain functioning. Here, we use a rat model ... -
Comparison of commercial ELISA assays for quantification of corticosterone in serum
(Peer reviewed; Journal article, 2017-07-27)Enzyme-linked immunosorbent assay (ELISA) kits are widely used to quantify corticosterone levels for the assessment of stress in laboratory animals. The aim of this experiment was simply to evaluate if four different and ... -
Compensatory task-specific hypersensitivity in bilateral planum temporale and right superior temporal gyrus during auditory rhythm and omission processing in Parkinson's disease
(Peer reviewed; Journal article, 2019)Persons with Parkinson’s disease have general timing deficits and have difficulties in rhythm discrimination tasks. The basal ganglia, a crucial part of Parkinson’s disease pathology, is believed to play an important role ... -
Functional connectome differences in individuals with hallucinations across the psychosis continuum
(Journal article; Peer reviewed, 2021)Hallucinations may arise from an imbalance between sensory and higher cognitive brain regions, reflected by alterations in functional connectivity. It is unknown whether hallucinations across the psychosis continuum exhibit ... -
Glutamatergic modulation of auditory cortex connectivity with attentional brain networks in unpredictable perceptual environment
(Journal article; Peer reviewed, 2020)In a stable environment the brain can minimize processing required for sensory input by forming a predictive model of the surrounding world and suppressing neural response to predicted stimuli. Unpredicted stimuli lead to ... -
Heroic music stimulates empowering thoughts during mind-wandering
(Peer reviewed; Journal article, 2019-07-16)It is generally well-known, and scientifically well established, that music affects emotions and moods. However, only little is known about the influence of music on thoughts. This scarcity is particularly surprising given ... -
Involvement of the default mode network under varying levels of cognitive effort
(Journal article; Peer reviewed, 2022)Everyday cognitive functioning is characterized by constant alternations between different modes of information processing, driven by constant fluctuations in environmental demands. At the neural level, this is realized ... -
Neocortical substrates of feelings evoked with music in the ACC, insula, and somatosensory cortex
(Journal article; Peer reviewed, 2021)Neurobiological models of emotion focus traditionally on limbic/paralimbic regions as neural substrates of emotion generation, and insular cortex (in conjunction with isocortical anterior cingulate cortex, ACC) as the ... -
The neurophysiological correlates of religious chanting
(Peer reviewed; Journal article, 2019-03-12)Despite extensive research on various types of meditation, research on the neural correlates of religious chanting is in a nascent stage. Using multi-modal electrophysiological and neuroimaging methods, we illustrate that ... -
Progressive modulation of resting‑state brain activity during neurofeedback of positive‑social emotion regulation networks
(Journal article; Peer reviewed, 2021)Neurofeedback allows for the self-regulation of brain circuits implicated in specific maladaptive behaviors, leading to persistent changes in brain activity and connectivity. Positive-social emotion regulation neurofeedback ... -
A systematic review of studies utilizing hair glucocorticoids as a measure of stress suggests the marker is more appropriate for quantifying short-term stressors
(Peer reviewed; Journal article, 2019-08-19)Quantitating glucocorticoids (GCs) in hairs is a popular method for assessing chronic stress in studies of humans and animals alike. The cause-and-effect relationship between stress and elevated GC levels in hairs, sampled ... -
Validation of peripheral arterial tonometry as tool for sleep assessment in chronic obstructive pulmonary disease
(Peer reviewed; Journal article, 2019-12-18)Obstructive sleep apnea (OSA) worsens outcomes in Chronic Obstructive Pulmonary Disease (COPD), and reduced sleep quality is common in these patients. Thus, objective sleep monitoring is needed, but polysomnography (PSG) ... -
When the statistical MMN meets the physical MMN
(Peer reviewed; Journal article, 2019-04-03)How do listeners respond to prediction errors within patterned sequence of sounds? To answer this question we carried out a statistical learning study using electroencephalography (EEG). In a continuous auditory stream of ...
