How is it that we hear a tune rather than the individual notes? This may seem like a silly question but a moment’s reflection shows that this observation is of profound importance. Each note is played individually and yet we ‘hear’ the tune. This is similar as to how we perceive moment from a series of static images that are sent to the visual cortex from the retina. Clearly this is evidence that the brain manipulates how ‘reality’ is perceived. It holds back information until it can be placed in context. But how does the brain know when to release the ‘packet’ of information when it has no (precognitive) awareness of when the tune will stop?
