Appearance of the wild boar brain

On eight brains of wild boars, the appearance of the exterior and interior brain structures was studied. The brain was preserved in the skull by formalin solution injection into the carotid artery. After having been set up for 4 months in a 5% formalin solution, the brain was removed in conjunction with the coverings. Subsequently, the brain was preserved in 5% formalin for 2 months. By careful dissection and elaboration of special preparations, the appearance of the grey and white substance of the brain, of the basal ganglia and of certain portions of the limbic system was studied. On the frontal and horizontal sections of the brain the appearance of the brain matter, of the basal ganglia and of the brain ventricles was studied. The exterior and interior morphology of the cerebellum was investigated on special preparations.
