Fig. 71. Dorsal view of the human midbrain and medulla oblongata 

 after the removal of the cerebellum and the roof of the fourth ventricle, 

 with the positions of the cranial nerve nuclei projected upon the surface. 

 The motor nuclei are indicated on the left side and the sensory nuclei on the 

 right. The somatic motor nuclei are indicated by circles, the general vis- 

 ceral efferent nuclei by small dots, and the special visceral efferent nuclei by 

 large dots. The general somatic sensory area is indicated by horizontal lines, 

 the visceral sensory area by double cross-hatching, and the special somatic 

 sensory area by open stipple. (Compare Figs. 77, 86, and 114.)
