I am using the app Waking up from Sam Harris. A lot of his guided meditations tell you to perceive the world as the raw data of experience, instead of perceiving objects and concepts. To illustrate gazing at your visual field and only observing the colours and contrast, not objects. It is reasonable to wonder if this can happen.
Where in the brain could this change possibly happen. I suppose it is higher-level vision processing. Signals from the retina are relayed further to LGN and the visual cortex, where they are mapped as states of what we are perceiving. Where can this change of perception happen?
EDIT that could possibly explain this is the so called feature integration theory, which states that feature are perceived early, automatically and in parallel, while objects are identified separately.
