The alpha rhythm (~10 Hz) is the most prominent oscillatory activity in the human EEG and has been closely linked to fluctuations in cortical excitability. In many visual attention and memory tasks, alpha activity becomes lateralized across hemispheres -- a pattern widely interpreted as reflecting the allocation of spatial attention. Recent studies suggest, however, that the effects of ongoing alpha rhythms on perception are better captured ...

Our subjective experience of the world as visually rich and detailed appears inconsistent with phenomena like change blindness and inattentional blindness. These illustrate that, in the absence of focused attention, individuals are prone to missing changes or objects that would otherwise be noticed. These findings suggest that attention is crucial for conscious perception, raising the possibility that our experience of visual richness might ...
