We clearly process information, the neurochemical signatures are a way neuronal communication occurs between modulars of the brain. We have at least 50 neuro communication chemicals, that is over 2,118,760 possible combinations, our brain is a biological-system with not two signals but over 2 million. I hypothesise that the brain is at least a bimillenniumary system. "At least" is relating to the fact that neurochemical communication is just a part of the brain as a whole.
