Beta and Gamma Dynamics in Attentional Networks Predict Conscious Reports.

Conscious perception is preceded by distinct patterns of brain activity that depend on whether attention is oriented to the correct location or must be reoriented. Using magnetoencephalography, the study examined neural oscillations before near-threshold visual targets. Validly cued targets (67% of trials) were preceded by early beta-band activity in the right superior parietal lobule about 58 milliseconds after the cue. Invalidly cued targets that were reported were preceded by later beta activity in the right temporo-occipital region, theta-gamma phase-amplitude coupling in the right lateral visual cortex, and low gamma coherence between that region and the left temporoparietal junction.
