Huxley theorized that our brain has a reducing valve. I was wondering if this has ever been anatomically proven (blood-brain barrier?)? He proposed that when we take hallucinogens, (I read this in his writings on mescaline) the reducing valve is opened allowing a wealth of non-essential information to flow into our brain. Also, does anyone know if brain activity levels rise during hallucinations?
Like Timothy Leary stated: Our brains are like an organic computer, we need boot it up sometimes and by using hallusinogens we can open files that can't be opened otherwise, we should keep in mind that some people are not capable to use these files...
