Phase one changes (1-2 days after onset) (n=2 patients) included red hypoxic and "ghost" neurons and other acute neuronal injury and spongiosis. However, while the human brain has more neurons than any extant NHP several mammalian species possess more neurons in both the CNS and the cerebral cortex, including the long-finned pilot whale, a species of dolphin with more neurons (37.29 billion) in the neocortex than any mammal studied to date and almost twice as many as humans (Figure 2 .

The main feature of the cerebral cortex is that it is made up of different layers of gray matter. These layers conform the structure of the cortex and define its structural and functional organization. Histology stains are used to colour different structures within the cells. the cerebral cortex contains eminences (termed gyri) and spaces separating these eminences (termed sulci) sulci include.

They are caused by occlusion of deep penetrating branches of major cerebral arteries and are particularly common in hypertension and diabetes, which are associated with severe atherosclerosis of small .

The axon of the granular cells enter the molecular layer and bifurcates, travel longitudinally within the folium of cerebral cortex. The cerebral cortex is an approximately 5-mm-thick layer of gray matter covering the entire surface of the cerebrum. This layer is thrown into complex folds, with elevations called gyri and grooves known as sulci.

The folds of the cerebellum are narrow and deep and the cortex is distributed peripherally and the white matter centrally. HM Learnings motor areas of cerebral cortex Khaled El-Sheikh OVARY Stained with haematoxylin and eosin G eneral view.
