Contribute, yes sure, but not as a timebase for compute and generating motor output. Upper motor neurons need amazingly tight coactivation to achieve fine temporal control of spinal motor neurons when throwing a fast ball—-well under a millisecond (William Calvin, The Throwing Madonna). I do not see any EEG patterns as causal in this context. Nor between retina and visual cortex. Arguing in your favor, rhythms may be important in getting closer to an adaptive coordination of activation and inhibition. Retinal waves during development are thought to contribute (controversially) to retinotopic maps. The big question again is How does the CNS-body achieve adaptive temporal integration and functional harmony? No one knows.
