= Whole brain death: state of total encephalic lesion (brainstem and cortical<br />

structures).<br />

From a clinical point of view, both “whole brain death” and “brainstem death”<br />

identify the definitive loss of wakefulness, consciousness, respiration and<br />

brainstem reflexes.<br />

We stress that the “brain” represents all of the parts of the central nervous<br />

system found in the cranium, which should be more properly called<br />

“encephalus” (from the Greek encephalon: “inside the head”). The cerebellum,<br />

scientifically, is the combination of telencephalon and diencephalon.<br />

- telencephalon: it is the most superficial part made up of the telencephalic<br />

cortex, the white substance and the base nuclei<br />

- diencephalon: it is situaied inside the telencephalic white substance, and it is<br />

made up of five parts (thalamus, epithalamus, metathalamus, hypothalamus,<br />

subthalamus), it carries on below with the mesencephalon through the two<br />

cerebral peduncles<br />

- cerebellum: the part of the encephalon situated in the posterior cranial fossa<br />

- brainstem: functionally connected with the cerebellum, it is itself made up of<br />

three parts, in the caudal-cerebral sense:<br />

- mesencephalon: higher continuation of the diencephalon, made up by the two<br />

cerebral peduncles and by the quadrigeminal plate;<br />

- pons: positioned ventrally to the cerebellum;<br />

- myelencephalon: also called midolla oblungata, which carries on below,<br />

without interruptions, with the spinal cord.<br />
