Associations between structural neuroimaging markers and neuropathology of Alzheimer’s Disease
Structural MRI is widely used for assessing the progression of Alzheimer’s disease (AD). However, postmortem pathological examination remains the gold standard for confirming the diagnosis. We systematically investigated associations of structural MRI markers with AD neuropathology in…

Neurophysiological signatures of rumination’s impact on opioid withdrawal severity
Opioid withdrawal symptoms (OWS) represent a major clinical challenge during abstinence, imposing physiological distress and increasing psychological vulnerability to relapse. Psychological factors contributing to individual differences in OWS severity remain understood, and reliable biomarkers for…

Dynamic causal modelling for functional near-infrared spectroscopy using spatial priors derived from diffuse optical tomography
Functional near-infrared spectroscopy (fNIRS) is an optical neuroimaging technique that measures brain activity by detecting changes in oxygenated and deoxygenated hemoglobin concentrations. Although methods exist for estimating causal interactions among brain regions using fNIRS data, current…

LS-MAT: Lifespan structural magnetic resonance imaging synthesis for microstructural covariance profile analysis toolbox
Human brain structure changes dynamically across the lifespan, closely linked to cognitive development and decline. T1-weighted and T2-weighted magnetic resonance imaging (MRI) are widely used to assess anatomical and microstructural properties. However, acquiring longitudinal multimodal MRI is…

Perceptual ambiguity of the self – dynamics connect brain and behaviour
When the distinction between self and other is blurred, the self-other boundary is weakened, introducing perceptual ambiguity. The neural and behavioural mechanisms of resolving this ambiguity, and their interaction, are not known. To address this, we used a facial morphing task recorded in EEG…

Optimal location for gesture decoding in the sensorimotor cortex and implications for brain-computer interface research
Implantable brain-computer interfaces (iBCIs) aim to restore communication in individuals with severe motor impairments. For good iBCI performance, it is important to target an optimal location. In this study, we used high-resolution 7-Tesla functional magnetic resonance imaging (fMRI) to map the…

Foreign language modulates neural responses to instructed fear: a neuroimaging study in bilinguals
The use of a foreign language has been shown to modulate emotional processing in bilinguals and has been associated with reduced emotional reactivity. A previous psychophysiological study investigating fear conditioning in bilinguals showed that receiving instructions on threat contingencies in L2…

Distinct and coordinated contributions of hippocampus and frontal eye field to novelty exploration and revisitation
Humans dynamically alternate between exploring novel information and revisiting familiar content, yet the neural mechanisms that separately govern these behaviors remain incompletely understood. In this study, we combined intracranial electrophysiology with eye-tracking to investigate the…

Limited cross-modal activation to visual language in the auditory cortices of hearing-impaired children
What predicts spoken language outcomes in hearing-impaired children has been insufficiently understood, particularly with respect to cross-modal neural activation and sign language input. This study assessed neural activation in the auditory cortices of Czech-learning preschoolers with cochlear…

Neural signature underlying the effect of intranasal vasopressin on emotional responses to spontaneous social comparison
Vasopressin, a key molecular regulator of social behavior, is implicated in promoting self-protective responses to threats against physical safety and resources. However, its role in defending against self-view threats—common in social interactions and critical to well-being—remains unclear. This…

Encoding of modality-specific face engrams promotes distinct recruitment of mnemonic processing mechanisms: A mobile-EEG study comparing encoding and retrieval of 2D and 3D avatars under virtual reality conditions
The processing of faces under realistic virtual conditions engages distinct cognitive mechanisms that are attuned to their inherent conceptual and socially relevant characteristics. To more closely approximate real-life circumstances of personal encounters, the degree of realism is increased by…

Diurnal changes of cerebrospinal fluid and global signal coupling
Cerebrospinal fluid (CSF) bulk movement around the brain is mediated by brain hemodynamics and has been linked to the brain´s waste clearance process and the so-called glymphatic system. Factors such as sleep have been demonstrated to influence global brain hemodynamics, including the coupling…

Cerebrovascular 5D flow MRI
Background: 4D flow MRI facilitates quantification of cardiac phase-resolved blood velocity vector fields and has successfully been deployed to study cerebrovascular flow. Besides cardiac-induced flow pulsation, respiration is known to modulate arterial and venous blood flow in the brain…

Connectome-based prediction of problematic use of social media in adolescents: Findings from the ABCD study
Problematic use of social media (PUSM) is a major public health concern estimated to affect 35% of adolescents. However, data-driven research to identify neural networks predictive of PUSM in adolescents remains limited. The aim of this study was to utilize connectome-based predictive modelling…

Contrast input and manual interventions significantly affect FreeSurfer morphometry and clinical correlations
FreeSurfer is a widely used software for quantification of brain morphometrics in studies of neurodegeneration and aging. However, choice of input MRI contrast(s) and manual editing are variable across studies and their influence on clinically relevant outcomes remains unclear. Using non-demented…

Gut unclassified Ruminococcaceae reweights cortical functional gradients and small-world topology with links to mood and diet
The microbiota-gut-brain axis is a key conduit linking metabolism, mood, and cognition; however, its position within the continuous functional hierarchy of the cortex and the underlying mechanisms are unclear. In this study, a cross-modal brain-gut dataset from 88 healthy male participants was…

The Erlangen Program in lateral occipital cortex: Hierarchical encoding of emergent features
Emergent features are fundamental concepts in Gestalt psychology, yet the neural encoding of these features, particularly a quantitative understanding of their relative superiority, remains elusive. This study bridges this gap by conceptualizing emergent features through geometric transformations…

Negative motor areas: functional connectivity using stereoelectroencephalography
Negative motor areas are cortical regions that, when stimulated, determine an inability to pursue voluntary movement or sustain voluntary muscle contraction without producing any other symptoms or signs. This is the first study that addresses the localization and functional connectivity of the…

Associations of hippocampal subfield volumes with psychiatric symptoms, childhood adversity and cardiorespiratory fitness in adolescents and young adults
Background: Reduced hippocampal volumes are frequently observed in psychiatric disorders and have been linked to childhood adversity. Conversely, physical activity is associated with increased hippocampal volumes. This study aimed to integrate these risk and protective factors in young people by…

Brain stimulation prevents neural downregulation and optimizes learning
Non-invasive brain stimulation, such as transcranial random noise stimulation (tRNS), has been shown to enhance cortical excitability and facilitate perceptual learning. However, the neural mechanisms underlying these effects remain poorly understood. Here, we demonstrate that tRNS over the…
