Question

What is CPH4 and what is its uses and from where it is found and how was it discovered

Answer 1

6-carboxy-5,6,7,8-tetrahydropterin is CPH4 in the body, involved in the process of biosynthesis of tetrahydrobiopterin, an essential cofactor of aromatic amino acid hydroxylases. It is not the substance that Freeman descries it to be, it has no direct neurologic effects.  So it does not work the way the movie described, nothing does. We use ALL of our brains, not just 10%.  What kind of evolutionary change would give us an organ in which only 10% of it was useful, for EVERYBODY? Especially the brain. 

There is no area of the brain that has not been neuroscientifically mapped, and virtually all areas have been functionally identified.  There isn't any area in the brain that is not in use for some mental or neurological purpose.  The closest we come to Freeman's idea of not all of the brain being used is when, say, looking at a painting, you not using the % of your brain concerned with auditory input (at the time). So yeah, our whole brain is not 100% active all at once, but it is all used, no part of the brain is just sitting there waiting to be activated.
