This study shows serotonergic psychedelics like LSD and DMT delay resting state neurovascular coupling, affecting hemodynamic delays and functional connectivity in brain regions with serotonin receptors.

The paper investigates associations between oculomotor responses during an oddball task and CSF biomarkers in MCI patients, finding p-Tau levels correlate with reduced cognitive vergence and pupil differentiation.

This paper introduces a modified neural mass model with inhibitory synaptic plasticity to better simulate EEG and fMRI recordings during NREM sleep and capture the spectral richness of brain activity.

This study uses cognitive vergence and pupillary responses during a visual oddball task to differentiate AT(N) biological profiles in MCI patients.

This study identifies genetic variants associated with Alzheimer's disease and frontotemporal dementia in admixed Latin American populations using whole-genome sequencing and ancestry analysis.

This study links cardiometabolic state, measured by an allostatic load index, with neurovascular burden and brain structure/function changes across age using EEG and MRI data.

This study uses a whole-brain model to show that video game expertise is linked to meso-scale functional connectivity changes and improved noise filtering in brain networks.

The paper maps brain states of reduced consciousness into a low-dimensional space using whole-brain modeling and deep learning, revealing an orderly trajectory from wakefulness to brain injury.

This paper uses deep learning models to analyze whole-brain dynamics in neurodegenerative diseases, identifying key regions for inducing transitions from pathological to healthy states.

The paper develops a framework to distinguish brain states by their stability and reversibility, using whole-brain models to analyze consciousness levels and their response to perturbations.

The paper compares neural activity during hypnotic hallucination, mental imagery, and visual perception, finding greater right-hemisphere top-down activation in hallucination.

This study investigates neural phase synchronization during visual face imagery, finding gamma-range long-range synchrony between frontoparietal and occipitoparietal regions and theta-range short-range frontal synchrony.

The paper examines neural information dynamics during bistable perception, finding distinct patterns of integration and differentiation in neural activity for endogenously and exogenously driven percepts.
