I. Note on some of the motor functions of certain cranial nerves (V, VII, IX, X, XI, XII), and of the three first cervical nerves, in the monkey ( Macacus sinicus )

Abstract

In the coarse of an investigation which we are making into the cortical representation of the muscles of the mouth and throat, we have experienced considerable difficulty in describing correctly the movements of these parts, especially when there was any question of bilateral action occurring. On referring to text-books we failed to find any solution of this difficulty, and we therefore determined to make a few observations of the movements evoked by stimulating the several cranial nerves supplying this region in the monkey so as to have a definite basis whereon to ground our observations of the movements obtained by stimulating the cortex.
