Beta, but Not Gamma, Band Oscillations Index Visual Form-Motion Integration
Only clusters of contiguous sources (n>50) with power greater than 50% of maximum activity are shown. A. Sources of gamma power (range 55–85 Hz) computed using all the trials are mainly located within the occipital lobe. B. Power differences between bound and unbound trials fail to reveal sources in the gamma band. C. Sources of beta power (15–25 Hz) computed using all the trials show decreased beta power over the left motor cortex, as expected given that observers used their right hand to report their perception. D. Sources of beta power computed from the differences between bound and unbound trials are mostly distributed over central-parietal cortex.
