The brain. (F.) Cerveau, Cervelle. This term is sometimes applied to the whole of the contents of the cranium: at others, to the upper portion ;-the posterior and inferior being called cerebellum. The brain, properly so called, extends from the os frontis to the superior occipital fossae. Anteriorly, it rests on the orbitar vault: behind this, on the middle fossae of the base of the cranium; and, posteriorly, on the tentorium cerebello superextensum. The upper surface is divided by a deep median cleft (Scissure interlobaire, - Ch.) into two halves, called hemispheres, which are united at the base by the corpus callosum. At its surface are numerous convolutions. The inferior surface exhibits, from before to behind, three lobes, distinguished into anterior, middle, and posterior. The middle is separated from the anterior by the fissure of SYLVIUS; and from the posterior, by a shallow furrow which corresponds to the upper portion of the pars petrosa. Internally, the brain has, on the median line, the corpus callosum, septum lucidum, fornix, pineal gland, and third ventricle: -and laterally, the lateral ventricles, in which are the corpora striata, optic thalami, &c. It is contained in a triple envelope, (see Meninges.) Its texture is pulpy, and varies according to age. Two substances may be distinguished in it -the white, medullary, tubular or fibrous- medull'a cer'ebri, (F.) Pulpe cerebral, and the cortical, cineritious, vesicular, or gray. The former is white; and occupies all the interior and base of the brain. The latter is grayish and softer. It is situate particularly at the surface of the organ. The brain receives several arterial vessels, furnished by the internal carotid and vertebral. Its veins end in the sinuses. It is the material organ of the mental and moral manifestations. According to Gall, each part is the special seat of one of those faculties, and the brain and cerebellum, inclusive, are called by him 'the nervous system of the mental faculties.' See Craniology. The substance of the nervous system-Neurine -has been analyzed by Vauquelin, and found to contain water, 80.00; white fatty matter, 4.53; red fatty matter, called cerebrine, 0.70; osmazome, 1.12; albumen, 7.00; phosphorus, 1.50; sulphur, acid phosphates of potassa, lime, and magnesia, 5.15.

The larger, superior part of the brain, consisting of two hemispheres, occupying the vault of the cranium and the anterior and middle fossae of its base. It consists of central white and cortical gray matter with special collections of gray matter. It is continuous posteriorly with the cerebellum and the medulla oblongata by a constricted portion called the isthmus. [Lat.]
