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.

This study finds that ABR latencies, not amplitudes, correlate with gray matter volumes in specific auditory pathway regions in older adults.

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 shows that aperiodic exponents of brain field potentials vary with frequency range, highlighting the need for consistent frequency range selection in neuroscience research.

The paper examines subcortical structures and auditory function in older adults with tinnitus, finding increased basal ganglia volume but no differences in auditory areas.

This study investigates how noradrenaline and acetylcholine influence functional connectivity during NREM sleep stages using a whole brain model and empirical data.

This study shows the thalamus controls cortical dynamics across conscious states using fMRI, electrophysiology, and biophysical modeling.

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 analyzes cochlear implant electrocochleography noise in humans and identifies a 3.1 kHz frequency peak potentially reflecting auditory-nerve spontaneous activity.

The paper investigates cochlear dysfunction as an early biomarker for cognitive decline in elderly individuals with normal or mild hearing loss, finding that DPOAE measurements correlate with cognitive and brain atrophy indicators.

This study investigates the relationship between 1/f slope and Lempel-Ziv Complexity in brain states using simulated and empirical data from rat EEG and monkey ECoG.

The paper uses inverted neural mass models to link electrophysiological signatures of awareness to thalamocortical mechanisms across arousal states.

This study examines oscillatory activity in tinnitus patients during auditory and visual attention, finding altered corticofugal pathways and increased theta power in frontal EEG regions.

This study uses empirical fMRI and computational modeling to show that nicotine increases functional segregation in the brain during attentional tasks but not at rest, linking network topology to behavior.

The paper examines how the ascending arousal system influences large-scale brain network integration during a visuospatial attention task, showing correlations with attentional load and receptor distribution.

This study identifies genetic variants linked to longitudinal brain structure changes across the lifespan using MRI data from 15,640 individuals.
