Characterising time-on-task effects on oscillatory and aperiodic EEG components and their co-variation with visual task performance.

This study examines how time-on-task influences oscillatory and aperiodic EEG components and their relationship with visual task performance, finding that alpha-band changes explain reaction time variability but not decision confidence.

Resting-state EEG signatures of Alzheimer's disease are driven by periodic but not aperiodic changes

The paper investigates whether Alzheimer's disease EEG changes are due to periodic or aperiodic signal alterations, finding they are purely periodic.

Reliability of resting-state EEG modulation by continuous and intermittent theta burst stimulation of the primary motor cortex: A sham-controlled study

This study examines the reliability of resting-state EEG modulation by cTBS and iTBS on the primary motor cortex, finding no significant group-level effects and low-to-moderate reliability across sessions.

History biases reveal novel dissociations between perceptual and metacognitive decision-making

The paper examines how choice history influences perceptual and metacognitive decision-making, finding dissociations that challenge existing theories of confidence.

Two distinct stimulus-locked EEG signatures reliably encode domain-general confidence during decision formation

The paper examines behavioural and EEG measures of metacognition across two cognitive domains, finding that metacognitive bias is reliable and domain-general, while efficiency is not, and identifying two EEG signatures linked to confidence.

EEG Alpha Power Predicts the Temporal Sensitivity of Multisensory Integration

The paper investigates how pre-stimulus EEG alpha power and frequency predict temporal sensitivity in audiovisual discrimination tasks using above-threshold stimuli.

Subjective perceptual experience tracks the neural signature of sensory evidence accumulation during decision formation

The paper investigates how the neural signature of sensory evidence accumulation (CPP) relates to subjective perceptual experience during decision formation, finding that CPP tracks subjective evidence levels.

Frequency and power of human alpha oscillations drift systematically with time-on-task

The paper shows that alpha oscillation frequency and power change systematically over time during an experimental session, with distinct patterns in different frequency bands.

Stimulus-driven brain rhythms within the alpha band: The attentional-modulation conundrum

The paper reconciles conflicting findings on attentional modulation of alpha-band brain rhythms by showing that different EEG analysis approaches reveal distinct effects of spatial attention on stimulus-locked and ongoing neural activity.

No changes in parieto-occipital alpha during neural phase locking to visual quasi-periodic theta-, alpha-, and beta-band stimulation

This study investigates whether low-intensity quasi-periodic visual stimulation affects parieto-occipital alpha rhythms, finding no evidence of entrainment.
