Coupled neuro-fluid dynamics in human bioelectromagnetism

This study challenges the assumption that EEG and MEG signals are solely generated by neural activity, showing that fluid motion in the brain can produce signals resembling M/EEG.

Misinterpreting electrophysiology in human cognitiveneuroscience

The paper challenges the direct interpretation of EEG components in cognitive neuroscience by showing they are indirectly linked to cognition through oculomotor actions, using 6 experiments with 204 participants.

Predicting driver distraction using a single channel ear EEG

This study decodes cognitive distraction during driving using single-channel in-ear EEG, showing comparable temporal dynamics to full-cap scalp EEG and highlighting eye velocity as an early behavioral marker.

The neuro-ocular costs of texting during driving

This study investigates the neurophysiological effects of texting while driving under different working-memory loads, finding altered reaction times, gaze behavior, and brain activity patterns.

Alpha/Beta oscillations reflect the dynamics of the oculomotor system: a new perspective on subsequent memory effects

This study links alpha/beta oscillations to oculomotor dynamics rather than memory performance, showing that eye movements drive alpha/beta power changes.

Species-conserved mechanisms of abstract rule learning promote cognitive flexibility in complex environments

This study identifies a species-conserved mechanism of hypothesis testing in rats and humans during rule learning, which enhances cognitive flexibility in complex environments.

Eye movements track prioritized auditory features in selective attention to natural speech

The paper shows that eye movements track acoustic features of attended speech, differentiating targets from distractors and relating to speech intelligibility.

Cortico-ocular coupling in the service of episodic memory formation

The paper shows that gaze variability and alpha/beta oscillation amplitude modulations in visual cortex predict memory performance and are functionally linked during visual information encoding.

Decomposing age effects in EEG alpha power

The paper investigates age-related changes in EEG alpha power by decomposing signals into aperiodic and adjusted components across three samples of young and elderly individuals.

Decomposing the role of alpha oscillations during brain maturation

This study decomposes alpha oscillation power into periodic and aperiodic components, revealing distinct developmental trajectories and linking periodic changes to thalamocortical connectivity and attentional performance.

Alpha oscillations link action to cognition: An oculomotor account of the brain's dominant rhythm

The paper proposes a new theory linking alpha oscillations to oculomotor control and cognition, showing how alpha power modulations relate to eye movements and working memory.

Sound-location specific alpha power modulation in the visual cortex in absence of visual input

This study shows that alpha power modulation in the visual cortex during auditory spatial attention is linked to oculomotor actions rather than just attentional filtering.

Alpha oscillations govern interhemispheric spike timing coordination in the honey bee brain

The paper identifies an alpha-like oscillation in honey bees that influences spike timing and gamma activity, suggesting a conserved role of oscillations in cognition across species.

Interpreting neural decoding models using grouped model reliance

This paper introduces grouped model reliance as a method to interpret neural decoding models, showing that alpha-band activity is consistently used but with inter-individual variability in frequency and topography.
