It illustrates the general relations of the termini of the gustatory fibers of the 

 vagus. Dorsally these root fibers form dense arborizations about cells of the dor- 

 sal secondary group of the vagal lobe {dorsal seen.), and ventrally about cells of 

 the lateral secondary group (lateral seen.). From the dorsal group neurites pass 

 downward and outward into the secondary gustatory tract [s.g.t.); from the later- 

 al group neurites pass to the opposite side through the ventral commissure (cf. 

 Fig. 33)-
