The ventricles of the human brain... are filled with hormones, and until the hormones swimming in these oceans are dredged out, countless millions of our fellows will remain with brain illnesses that can be neither understood nor treated. Many of their hormone-hungry brains may be fixed as easily as hormone-hungry bodies are fixed with thyroid hormone, insulin, oestrogen and testosterone, but that work cannot begin until cause and effect relationships between brain hormones and brain diseases have been established.
The brain has all the characteristics of a gland except one—leaky capillaries—the sturdy brain capillaries are collectively called the 'blood-brain-barrier'. This barrier can easily be demonstrated by injecting a blue dye into an animal; every other organ (except the testicle) turns blue, but the blood-brain barrier keeps the brain as white as snow.
It would be easier... if all animals spoke the same endocrine language, for then correlations made in the laboratory could be quickly moved to the bedside. Unfortunately, such is not the case. The hormone prolactin, for example, has at least seventy-eight different functions in seventy-eight different species
In the past decade, as regulating hormones have been found throughout the body, the soul has lost its home. It is scattered everywhere—in the brain, the gut, the ovary, the pituitary and the adrenal; if paracrinologists are correct, every cell contains the well-chiselled molecules that give life to the soul and guidance to the mind.
