Ivan Pavlov Quotes

As was to be expected, the discovery of the nervous apparatus of the salivary glands immediately impelled physiologists to seek a similar apparatus in other glands lying deeper in the digestive canal.

Although it's the hub of the nervous system and the ultimate terminus of every nerve, the brain itself lacks enervation and therefore cannot feel pain.

Now, there are a very large number of bodily movements, having their source in our nervous system, that do not possess the character of conscious actions.

The thing I'm most interested in is the nervous system. How do brains grow? How do genes build complicated nervous systems?

The body and dendrites of a nerve cell are specialized for the reception and integration of information which is conveyed as impulses that are fired from other nerve cells along their axons.

Our bodies are finely tuned machines, and if our hormone mixtures aren't 'just right', everything goes into disrepair.

Your immune cells are like a circulating nervous system. Your nervous system in fact is a circulating nervous system. It thinks. It's conscious.

Physiology has, at last, gained control over the nerves which stimulate the gastric glands and the pancreas.

In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

When you suffer an attack of nerves you're being attacked by the nervous system. What chance has a man got against a system?

Our entire personality, our energy level, and how we cope is hormonal.

Researchers have found that the brain definitely sends nerves directly to organs of the immune system and not just to the heart and the lower gut. In that way, too, the brain is influencing the body.

The amygdala in the emotional center sees and hears everything that occurs to us instantaneously and is the trigger point for the fight or flight response.

We shall probably never attain the power of measuring the velocity of nervous action; for we have not the opportunity of comparing its propagation through immense space, as we have in the case of light.

What we feel and think and are is to a great extent determined by the state of our ductless glands and viscera.

In the year 1921, I was successful for the first time in obtaining certain proof that by stimulation of the nerves in a frog's heart, substances were released which to some extent passed into the heart fluid and, when transferred with this into a test heart, caused it to react in exactly the same way as the stimulation of the corresponding nerves.

The mind and the body are inextricably entwined, and rarely are their inseparability clearer than when we're under some kind of mental pressure. The moment we start trying to learn a new skill, make a decision or otherwise think on our feet, our nervous system reacts - with accelerated pulse rate, increased respiration, even sweating.

To speak, therefore, of an electric current in the nerves, is to use quite as symbolic an expression as if we compared the action of the nervous principle with light or magnetism.

There are many ways in which genes influence the brain.

Adrenaline is an amazing thing.

I think what's known about neurology is still scattered and uncertain.

I wanted to be a neurologist. That seemed to be the most difficult, most intriguing, and the most important aspect of medicine, which had links with psychology, aggression, behavior, and human affairs.

I've always been fascinated with adrenaline; it's saved my life more than once, and it's caused me to need it to save my life more than once. One of the most fascinating responses in human evolution, adrenaline sharpens your brain; it sharpens your responses.

Information is crucial to our biological substance - our genetic code is information. But before 1950, it was not obvious that inheritance had anything to do with code. And it was only after the invention of the telegraph that we understood that our nerves carry messages, just like wires.
