Which nutrient contains the greatest number of calories per gram?

Through the postmortem study of the brains of people who have experienced brain injury

or damage, it is possible to correlate specific behaviors with specific regions of the brain. Psychologists and physiologists who study the relationship of behavior and brain function in this way are building upon the earlier work of a. Helmholtz. b. Flourens. c. Broca. d. Galvani. e. Müller.

Helmholtz's finding that the nerve impulse traveling through the body is considerably

slower than electricity traveling through a wire, led to the important realization that a. the nerve impulse is not electrical in its nature. b. nerve impulses are more complex than simple electrical current. c. specific structures within the body impede the speed with which electrical current travels through the nervous system. d. the brain and nervous system could be studied safely by stimulating them with weak electrical current. e. electrical stimulation of the body could potentially damage the nervous system.
