I am interested in creating an actual/metaphorical parallel from the psychedelic state to the phenomenon of 'blindsight.' Perhaps you can help.
The psychedelic state can be characterized by a unique awareness of a reality, extra-sensory, extra-dimensional, other-worldly(?).
Blindsight is a bizarre phenomenon wherein a person has access (on a computational/unconscious level) to visual information, but is not aware (phenomenally) of it. Flash a card with a number on it in front of a person suffering from blindsight and while they are not consciously aware of what you are doing, they can still tell you, far greater than probability allows, what number is on the card. There is a bit of neuroscience to back this up. What is likely the case in these people, is that all (or most) of their early visual cortices are damaged, thus barring the possibility for them to form a visual image of the card. However, as long as other, collateral, structures responsible for mental representation/computation are uninjured (as well as the requisite visual apparatus, retina, nerve structure, etc) the person will still receive the raw data of the card (in the form of a retinal image), preform a quick (haha) operation of inverse optics on the image, translating it to a raw form of mental language, and process it through the appropriate structures (parietal cortices, thalamus, etc). What will result, of course, are mental representations of the card, only minus the accompanying 3d image of it. Thus a person sees without experiencing seeing.
Do psychedelics open us up to seeing something that we are always seeing just unaware of?
Do psychedelics allow us to use our brain structures in a way that we normally do not?
Are psychedelics affecting the evolutionary process of the human organism?
Your thoughts, please!
