The treatment of aphasias and the development of the oppo-site-sided speech-centers have been described in the chapter on Aphasia.

The return circulationfrom the ventricular portion of the cerebrum and the callosal portionof the hemispheres is by the Gallenic veins and inferior longitudinalsinus, all of which empty into the straight sinus. From the convexitythe pial veins run upward and open into the superior longitudinal sinus Communication, through-parietal foramen with external veins of skull.

Here the circulatory conditions are rendered still moreunfavorable by hydrostatic pressure, by the presence of trabecular in thesinuses which impede the flow of blood, and by venous retardationduring inspiration. The cerebellar veins empty mainly into the lateralsinuses. Into the dural sinuses also empty many veins from the faceand scalp. The facial vein communicates with the cavernous sinusthrough the ophthalmic vein. The veins of the nasal vault open intothe anterior extremity of the superior longitudinal sinus. Xumerousveins of the scalp along the median line have a similar outlet.
