choroideus, gyrus hippocampi, and fimbria and fascia dentata 

 hippocampi. 



Include and name other gyri and sulci involved in the sec- 

 tion. 



What is the relation of the tractus opticus to the pulvinar ? 

 What is the' nature of the lining of the ventriculus lateralis ? 

 What is the function of the corpus callosum ? What is the rela- 

 tion of the pedunculus cerebri to the capsula interna ? Look for 

 the commissura posterior. This may have been removed with 

 the mesencephalon and corpus pineale. 



Section 15, to pass through the corpus mamillare, the massa 

 intermedia, and the anterior portion of the lobulus paracentralis. 



Draw, giving special attention to the following structures : 



Corona radiata, capsula interna, corpus callosum, columna 

 fornicis, ventriculus tertius, massa intermedia (middle commis- 

 sure), thalamus opticus, stratum zonale, lamina medullaris, and 

 stria medullaristhalami; nucleus hypothalamicus, basis pedunculi, 

 tractus opticus, and corpus mamillare. 



Corpus striatum and radiatio corporis striati. 



Insula, gyri insulae, claustrum, capsula externa, nucleus lenti- 

 formis, composed of putamen and globus pallidus. Ventriculus 

 lateralis with its pars centralis under the corpus callosum and its 

 cornu inferius containing the hippocampus. Look for the fasci- 

 culus thalamo-mamillaris. 



What is the relation of the corpus mamillare to the fornix 

 and to the thalamus ? By what fibers is the substantia corticalis 

 connected with the ganglia below and with the medulla oblongata ? 

 What is the nature of the claustrum? What is the difference 

 between the capsula interna and externa ? What masses com- 

 pose the corpus striatum ? 



Attach the names of all gyri and sulci involved in the section. 



Section 16, to pass through the chiasma opticum and the 

 commissura anterior. 



Draw, giving special attention to the following structures : 



Corpus callosum, columna fornicis, ventriculus lateralis 

 (cornu anterius), septum pellucidum, plexus choroideus.
