In every instance the loss of vitality—that is, the loss ofthe normal power to convert potential into kinetic energy—was accompanied by physical changes in the brain-cells(Figs. 45 and 4(i). The converse was also true, that is, thebrain-cells of animals with normal \ital power showed nohistologic changes.

The crucial question thenbecomes: Are these constant changes in the brain-cells theresult of work done by the brain-cells in running, in fighting,in emotion, in fever?
