For over two billion years, through the apparent fancy of her endless differentiations and metamorphosis the Cell, as regards its basic physiological mechanisms, has remained one and the same. It is life itself, and our true and distant ancestor.

The living cell almost always contains, locked in its interior, the visible or invisible products of its physiological activity or its nourishment.

This substance, which is manifold in its forms and protean in its transformations, has, in its state of living matter, one physiological name which has become familiar, that of protoplasm.

After asking questions about current recovery techniques, the conversation prompted me to ask myself, 'Why does it feel good after running to pour a bottle of water over your head?' I don't know the physiological answer, but the fact that it does feel better makes me perform better.

Rather than realizing immediate physiological gain, the challenge is more about reducing the mental attrition from the two days to maximize each event.

The constancy of the blood sugar level is maintained by a complex physiological mechanism, a homeostatic mechanism of the same order as those which maintain the body temperature, the blood pressure or the heart rate at normal levels and control many other functions.

Feelings aroused by the touch of someone's hand, the sound of music, the smell of a flower, a beautiful sunset, a work of art, love, laughter, hope and faith - all work on both the unconscious and the conscious aspects of the self, and they have physiological consequences as well.

Success and failure are emotional and physiological experiences. We need to deal with them in a way that is present and calm.

I'm developing a physiological theory of growth and oxygen requirement. If it's well-understood how fish require oxygen to grow, then we can understand how to deal with the impact of global warming.

Seeing is more than a physiological phenomenon... We see not only with our eyes but with all that we are and all that our culture is. The artist is a professional see-er.
