On the descending connections of the visual hillock

Abstract

At present, it seems more or less established the interruption of the fibers of the loop layer in the visual hillock. This proves the anatomical aspect of the relationship of visual hillocks to the sensitivity function, which is confirmed by both the newest pathological observations, especially Dejerine s, and experimental work. But the same cannot be said about the centrifugal connections of the visual hillock, which until now have remained little understood, despite the fact that the meaning of visual hillocks as centers of involuntary movements (mimic and movements of internal organs) was proved for the first time by me, and after that the authors in a whole series of experiments and observations. Some authors, like Probst, even deny completely on the basis of their research the existence of descending connections of the visual hillock, although it is absolutely impossible to agree already in the form of experimental data, which put outside doubt not only the sensitive, but also the motor function of the vision.
