Consciousness and Rhythm
Brain oscillations reveal that our senses do not experience the world continuously
Testing subsequent visual perception, by using transcranial magnetic stimulation of the visual cortex, revealed a cyclic pattern at the very rapid rate of brain oscillations, in time with the underlying brainwaves. Prof Thut said: “Rhythmicity therefore is indeed omnipresent not only in brain activity but also brain function. For perception, this means that despite experiencing the world as a continuum, we do not sample our world continuously but in discrete snapshots determined by the cycles of brain rhythms.” The research, ‘Sounds reset rhythms of visual cortex and corresponding human visual perception’ is published in the journal Current Biology.

This is more support for what I have been calling subtractive mechanics. The idea that subjectivity is not only built from the bottom up from meaningless parts and pixels but elided from the top down as well.
Just as our optical blindspot is erased through a filling in of high level perceptual expectations, our entire experience of life is a process of extracting signifying themes from many oscillating channels of sense. The realism we experience persists through time, within each moment accumulating the sense of the past and anticipating the intentions of our different sense-motive modalities. We are seeing through the oscillations, bridging each gap in sensation with ourselves – weaving ourselves into our experience .
This is the same thing I mean by the ‘Big Diffraction‘; the presence of everythingness bleeding through the gap between itself and its own absence, seeking to re-member its wholeness.
