It is what we have learned to call the mind that seems to focus attention. The mind is aware of what is going on. The mind reasons and makes new decisions. It understands. It acts as though endowed with an energy of its own. It can make decisions and put them into effect by calling upon various brain mechanisms. It does this by activating neurone-mechanisms [linguistic neural codes of the liaison brain transmitted with meaning and purpose through the synaptic neural networks]. This, it seems, could only be brought about by expenditure of [both nonclassical and classical electrochemical] energy. (Dr. Penfield)
