The section passes through the cephalic part of the facial lobe and includes the extreme cephalic end of the vagal lobe and the caudal end of the tuberculum acusticum. It shows five chief secondary gustatory neurones at the surface of the lobe and internally at a an imperfect impregnation of a cell of the interme- diate zone of the same type shown in Fig. 18, a. , main ascending secondary gustatory tract; , fasciculus longi- tudinalis medialis ; , communis (gustatory) root of the facialis; mot., motor root of the glossopharyngeus; Jtv.

The center of the lobe is filled with very small intrinsic neurones arranged in dense clusters or rosettes of from 10 to 100 cells each. In Fig. 5 the clear spaces in the neuropil of the.
