There are certainly oscillation but they are not a timebase for CNS compute—two orders of magnitude too slow. Despite Buzsaki best tries to explain in part with gamma oscillations. Some auditory binaural computes are at the microsecond level—-the owl catching the mouse mid-flight at night. Or you speaking or thinking rapid fire. That it in the millisecond domain.
- daveguy 3y agoJust because they aren't any faster than 80 hz doesn't mean they don't provide timing for compute. Like the GPS pulse per second doesn't provide the clock frequency, but it does provide the synchronization. Of course it's not digital precision, but how could it not contribute as an integral part of brain function?
- robwwilliams 3y agoContribute, 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.
