When people say that the human mind and the brain are two sides of a coin, they are not far from the truth. As an organ, the brain facilitates the functions of the mind. And we know that whatsoever alters the function of the brain affects the mind.
Also, the chemicals that facilitate human behaviour through the brain and allied structures are regulated by a physiological system that does not require supply from extraneous sources, except when drugs are prescribed to treat an ailment.
