It must be born in mind that one does not see directly - as is the case in the exploration of the surface of the brain - where the electrodes are attacking.

For man also, in health and sickness, is not just the sum of his organs, but is indeed a human organism.

The goal of physiological research is functional nature.

Exact information about the functional significance of the deep sections of the brain is only obtained by working through the brain histologically in serial section.

At the beginning of all experimental work stands the choice of the appropriate technique of investigation

It must be born in mind that one does not see directly - as is the case in the exploration of the surface of the brain - where the electrodes are attacking.

In fact, quantitative findings of any material and energy changes preserve their full context only through their being seen and understood as parts of a natural order.
