The mid-brain is built up of the pedunculi cerebri, passing from the pons to the cerebrum ; the corpora quadrigemina, forming its dorsal part; and the brachia conjunctiva ( superior cerebellar peduncles), proceeding from the cerebellum to the cerebrum. It is tunnelled by a narrow passage, the aquseductus cerebri, which extends between the fourth and third ventricles. In a view of the intact brain the greater part of the mesencephalon and diencephalon is hidden by the cerebral hemispheres; but a precise idea will be obtained of the inter-relationships of the various parts of the brain, if we study Foramen interventrieulare Lamina eommissurce hippocampi at the attach- ment of the epithelial roof of third ventricle Corpus callosum ,' Columna fornicis â ! , Septum pellucidum ; ; '. ; Anterior commissure â\âiâjâ( Epithelial roof of third ventricle Lamina commissuree hippocamp !
