OBSERVATIONS CONCERNING THE CEREBELLUM. DR. HILPERT, JENA.
The phylogeny of the cerebellum is described. This organ is part of a coordinative mechanism which automatizes and synergizes movements that originate as a psychic process which is eventually replaced by the establishment of the automatic and more rhythmic process, the latter being more economic of energy.
1. Spine, through (a) the dorsal lateral cerebellar tract, (b) the ventral lateral cerebellar tract, (c) the tracts from the funiculi gracilis and cuneatus; also fiber systems representing principally secondary neurons of the posterior roots.
2. Nuclei of the vestibular system, carrying equilibrial and tonus impulses.
3. Cerebrum, carrying voluntary motor impulses.
4. Midbrain over the lower olivary body, through the central bundle of the tegmentum, carrying reflex stimuli.
The cerebellum is a cerebral ganglion, i. e., neither a center of autonomic innervation nor a pure reflex organ. It operates
