Higher resting-state alpha power predicts greater cortical excitability for phosphene thresholds, but not motor thresholds.
No correlation found between alpha activity and perceptual abilities across various visual tasks.
Study utilized EEG recordings from 302 participants to explore alpha-band activity's influence on perception.
Findings suggest the relationship between alpha power and visual perception may be intra-individual rather than inter-individual.
