“The measurement of hormones in the bloodstream of patients will not reflect the endocrine activity of the brain.”

“Physicians and scientists will measure brain hormones—in ventricular fluid and elsewhere—will link these to specific diseases, and will devise space-age techniques to restock the mind's hormonal pantries. The only question is, When?'”

“The brain remains silently separated from the noisy endocrine consequences.”

“Brain/body relationships might depend upon a chorus of individual hormones... which are released together to sing hormonal harmonies to the body.”

“Our stay-put behavior reflects our view that the stock market serves as a relocation center at which money is moved from the active to the patient.”

“In decades to come ventricular catheterization performed to measure hormone concentrations will become as routine as the measurement of lumbar 'pressure' is today.”

“The hormonal genies that have lived unnoticed in the brain since humankind began have escaped; there is no way that they can be put back.”

“Humour is by far the most significant activity of the human brain.”

“… when dogma enters the brain, all intellectual activity ceases.”
