Maybe the isolated energizing of specific parts of the brain are misleading. What if the brain is stimulated not by just the usually accepted sensory inputs, but by many subtle bits of information from the endocrine system, the blood, and other organic functions. These multiple, intertwined flows of influence, coiled with memory may be a partial explaination of both mind and agency. Essentially, I am suggesting that the brain is not the sole place the mind occupies, but it is the whole body, including experience and memory that together create and nourish the mind.
