Functional brain networks in the schizophrenia spectrum and bipolar disorder with psychosis
(Journal article; Peer reviewed, 2020)Psychotic experiences have been proposed to lie on a spectrum, ranging from subclinical experiences to treatment-resistant schizophrenia. We aimed to characterize functional connectivity and brain network characteristics ... -
Functional changes in GABA and glutamate during motor learning
(Journal article; Peer reviewed, 2023)Functional magnetic resonance spectroscopy (fMRS) of GABA at 3 T poses additional challenges compared with fMRS of other metabolites because of the difficulties of measuring GABA levels; GABA is present in the brain at ... -
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 ... -
GABA, glutamatergic dynamics and BOLD contrast assessed concurrently using functional MRS during a cognitive task
(Journal article; Peer reviewed, 2023)A recurring issue in functional neuroimaging is how to link task-driven haemodynamic blood oxygen level dependent functional MRI (BOLD-fMRI) responses to underlying neurochemistry at the synaptic level. Glutamate and ... -
Gender stereotypes and incremental beliefs in STEM and non-STEM students in three countries: relationships with performance in cognitive tasks
(Journal article; Peer reviewed, 2021)Women’s underrepresentation in science, technology, engineering and mathematics (STEM) has been linked, among others, to gender stereotypes and ability-related beliefs as well as gender differences in specific cognitive ... -
Gender-stereotyping and cognitive sex differences in mixed- and same-sex groups
(Peer reviewed; Journal article, 2014-06-13)Sex differences in specific cognitive abilities are well documented, but the biological, psychological, and sociocultural interactions that may underlie these differences are largely unknown. We examined within a biopsychosocial ... -
Genome-wide analyses of aggressiveness in attention-deficit hyperactivity disorder
(Peer reviewed; Journal article, 2016-03-29)Aggressiveness is a behavioral trait that has the potential to be harmful to individuals and society. With an estimated heritability of about 40%, genetics is important in its development. We performed an exploratory ... -
Ghrelin is related to lower brain reward activation during touch
(Journal article; Peer reviewed, 2023)The gut hormone ghrelin drives food motivation and increases food intake, but it is also involved in the anticipation of and response to rewards other than food. This pre-registered study investigated how naturally varying ... -
Glutamate- and GABA-Modulated Connectivity in Auditory Hallucinations—A Combined Resting State fMRI and MR Spectroscopy Study
(Journal article; Peer reviewed, 2021)Background: Auditory verbal hallucinations (AVH) have been linked to aberrant interhemispheric connectivity between the left and the right superior temporal gyrus (STG), labeled the interhemispheric miscommunication theory. ... -
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 ... -
Goal management training for adults with ADHD – clients’ experiences with a group-based intervention
(Journal article; Peer reviewed, 2021-02-19)Background: There is growing evidence for the efficacy of group-based interventions for adults with ADHD. However, there is still a lack of research investigating how clients experience participating in such interventions. ... -
Goal management training improves executive control in adults with ADHD: an open trial employing attention network theory to examine effects on attention
(Journal article; Peer reviewed, 2022)Background Adults with Attention-Deficit/Hyperactivity Disorder (ADHD) typically experience poorer attentional control. According to the attention network theory, attentional control relies on three interacting networks ... -
Grammatical development in both languages of bilingual Turkish-Dutch children with and without Developmental Language Disorder
(Journal article; Peer reviewed, 2022)Introduction: To guarantee a reliable diagnosis of Developmental Language Disorder (DLD) in bilingual children, evaluating both languages is recommended. However, little is known about how DLD impacts the heritage language, ... -
Group Study of Simulated Driving fMRI Data by Multiset Canonical Correlation Analysis
(Peer reviewed; Journal article, 2011)In this work, we apply a novel statistical method, multiset canonical correlation analysis (M-CCA), to study a group of functional magnetic resonance imaging (fMRI) datasets acquired during simulated driving task. The M-CCA ... -
GWAS meta-analysis reveals novel loci and genetic correlates for general cognitive function: a report form the COGENT consortium
(Peer reviewed; Journal article, 2017-01-17)The complex nature of human cognition has resulted in cognitive genomics lagging behind many other fields in terms of gene discovery using genome-wide association study (GWAS) methods. In an attempt to overcome these ... -
Hallucinations in healthy older adults: An overview of the literature and perspectives for future research
(Peer reviewed; Journal article, 2017-07-07)Studies suggest a substantial minority of healthy older adults have hallucinatory experiences, in line with existing evidence on hallucinations in other age groups, though it is still unclear if hallucination prevalence ... -
Hallucinations in older adults: A practical review
(Journal article; Peer reviewed, 2020)By 2050, it is estimated that 16% of people will be aged above 65 years, compared with 9% in 2019.1 Population aging is driving increased attention to the physical and mental health needs of older adults. Here, our focus ... -
Hallucinations under psychedelics and in the schizophrenia spectrum: An interdisciplinary and multiscale comparison
(Journal article; Peer reviewed, 2020)The recent renaissance of psychedelic science has reignited interest in the similarity of drug-induced experiences to those more commonly observed in psychiatric contexts such as the schizophrenia-spectrum. This report ... -
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 ... -
High levels of childhood trauma associated with changes in hippocampal functional activity and connectivity in young adults during novelty salience
(Journal article; Peer reviewed, 2023)Childhood trauma (CT) has been linked to increased risk for psychosis. Moreover, CT has been linked to psychosis phenotypes such as impaired cognitive and sensory functions involved in the detection of novel sensory stimuli. ...
