The fate of the physiology of the brain is independent of the truth and falsity of my assertions relative to the laws of the organization of the nervous system, in general, and of the brain...

A recognized fact which goes back to the earliest times is that every living organism is not the sum of a multitude of unitary processes, but is, by virtue of interrelationships and of higher and...

In a world of seven billion people, where every inch of land has been mapped, much of it developed, and too much of it destroyed, the sea remains the final unseen, untouched, and undiscovered wilderness,...

The idea that the bumps or depressions on a man’s head indicate the presence or absence of certain moral characteristics in his mental equipment is one of the absurdities developed from studies in this field...

One of my friends compared me to Bruce Banner, due to my work with radiation and human health. So I looked up Bruce Banner and this is what I found: Banner, a physicist, is sarcastic...

All men are born firstly with the instinct to protect themselves. But few grow to really love themselves, and even fewer learn to love their neighbor as themselves.

Those who have dissected or inspected many [bodies] have at least learnt to doubt; while others who are ignorant of anatomy and do not take the trouble to attend it are in no doubt at...

Anatomy is to physiology as geography is to history; it describes the theatre of events.

Scientific physiology has the task of determining the functions of the animal body and deriving them as a necessary consequence from its elementary conditions.

Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don’t have much to do with evolution – they’re observations about the details of physiology, biochemistry, development,...

The Tarahumara would party like this all night, then rouse themselves the next morning to face off in a running race that could last not two miles, not two hours, but two full days. According...

I would not be among you to-night (being awarded the 1964 Nobel Prize in Physiology or Medicine) but for the mentors, colleagues and students who have guided and aided me throughout my scientific life. I...
