Although the content of consciousness depends in large measure on neuronal activity, awareness itself does not.To me, it seems more and more reasonable to suggest that the mind may be a distinct and different essence.

The brain has not explained the mind fully.

Brain surgery is a terrible profession. If I did not feel it will become different in my lifetime, I should hate it.

Canadian weather resembles a slightly spoiled beautiful girl with a good heart, but a bad disposition. After being horrid for much too long a time, she suddenly turns right about and makes up for everything with so much charm that you vow again you always loved her!

Among the millions of nerve cells that clothe parts of the brain there runs a thread. It is the thread of time, the thread that has run through each succeeding wakeful hour of the individual.

It is fair to say that science provides no method of controlling the mind. Scientific work on the brain does not explain the mind-not yet.

The problem of neurology is to understand man himself.

I realized that there was a thrilling undiscovered country to be explored in the mechanisms of the mammalian nervous system. Through it, one might approach the mystery of the mind.

Mind, brain, and body make the man, and the man is capable of so much!

The brain is the organ of destiny. It holds within its humming mechanism secrets that will determine the future of the human race.

Rest, with nothing else, results in rust. It corrodes the mechanisms of the brain. The rhubarb that no one picks goes to seed.

My plea to educators and parents is that they should give some thought to the nature of the brain of a child, for the brain is a living mechanism, not a machine. In case of breakdown, it can substitute one of its parts for the function of another. But it has its limitations. It is subject to inexorable change with the passage of time.
