The paper investigates phase-dependent perceptual biases during speech categorization and finds item-specific theta-gamma phase-amplitude coupling linked to neural and perceptual responses.

The paper tests a two-stage model of perceptual filling-in by examining how early visual cortex properties like the oblique effect and surround suppression influence the phenomenon.

This study investigates perceptual filling-in in human V1 using fMRI, finding that deep cortical layers show neural correlates associated with feedback input during the phenomenon.

The paper shows that gamma synchrony in the visual cortex depends on stimulus features and distance, aligning with weakly coupled oscillator theory and predicting human performance in texture segregation tasks.

This study examines alpha-theta cross-frequency dynamics during working memory and finds reduced inter-areal connectivity despite increased 2:1 frequency ratios.

The paper investigates how training and reminders affect visual skill learning, finding that reminders can be as effective as full training in certain contexts.

This study investigates how eccentricity and movement of visual stimuli affect perceptual filling-in by measuring neural adaptation in early visual areas.

The paper analyzes sleep spindle activity in human anterior thalamus and cortex using EEG and DBS recordings, finding coordinated patterns and frequency-dependent topography.

This study uses experimentally constrained computational models to analyze how contrast affects gamma rhythm instability in V1, finding that increased input heterogeneity disrupts inhibitory cell pacemaker function.

This study shows that somatosensory experience in adult rats alters white matter structure and myelin-related gene expression, suggesting myelination as an underlying mechanism.

This paper combines gamma, alpha, and beta power modulation from ECoG during cognitive tasks to improve identification of eloquent cortical areas in epilepsy patients, showing enhanced diagnostic performance over gamma alone.
