Fig. 12. Section through the vagal lobes. The section is slightly inclined, the left side being farther 

 toward the head and including the extreme caudal tip of the tuberculum acusticum. On the right 

 side the general cutaneous root of the vagus is seen entering the spinal V tract dorsally of the gustatory 

 vagus root for the vagal lobe. The small amount of grey among the fibers of the dorso-lateral fasciculus 

 is an extension from the funicular nucleus (cf. Fig. 11). 



Fig. 13. Section through the tuberculum acusticum to illustrate the composition of the fasciculus 

 dorso-lateralis at the level of the origin of the IX nerve. Dorsally are the spinal V tract and the tractus 

 cerebello-spinalis; ventrally is the ascending secondary gustatory tract. The fibers between, designated 

 jaic. dorso-lateralis, are fasicuclus lateralis fibers of mixed character, between the oblongata and the 

 spinal cord.
