Encephalic ventricles of the ewe (Ovis aries L.): conformation, relations and stereotaxic topography.

Fifteen ewes, aged 3-6 years, were used for studying the conformation of the cerebral ventricles on mouldings, and the topography on scannographs and frozen cuts. The lateral ventricles show important variations, but the topography of their olfactory recess is constant.
