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.

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

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.

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.

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

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.
