Accurate very high definition brain 3D model. A sectioned version and a closed version are included.Also included are the textures for a version with number on the surface of the different parts of the brain, a text document with the names for the numbered parts of the brain and textures for a version without numbers.
The model has been created using a 3D scan of a anatomical correct brain model as reference.
The extremely high detail is achieved by using high resolution normal bump maps. This way the rendering speed is very fast while you have an amazingly detailed model. As the textures have a size of 2048x2048 pixels, close up renderings are possible.
Max 9.0 Format:
Meshsmooth is applied so you can set the object resolution as you like.
Maya 8.0 Format:
Poly Smooth is applied so you can set the object resolution as you like.
Cinema 4D 9.6 Format:
The model is available in 3 different resolutions ranging from 23899 to 381872 Polygons. The lowest poly-version is the SubD. hull. So you can use it easily as SubD in any Software supporting SubD.

The brain is the main part of the central nervous system. Talking about the presence of the brain in the strict sense can only be applied to vertebrates, starting with fish. However, this term is used somewhat loosely to refer to similar structures of highly organized invertebrates — for example, in insects, the brain is sometimes called the accumulation of the glands of the pharyngeal nerve ring. When describing more primitive organisms, they speak of head ganglia, and not of the brain.
The weight of the brain as a percentage of body weight is 0.06—0.44% in modern cartilaginous fishes, 0.02—0.94% in bony fish, 0.29—0.36% in caudate amphibians, 0 in tailless 50—0.73%. In mammals, the relative size of the brain is much larger: in large cetaceans, 0.3%; in small cetaceans - 1.7%; in primates 0.6–1.9%. In humans, the ratio of brain mass to body weight is on average 2%.
The brain of mammals of the orders of cetaceans, proboscides, and primates has the largest sizes. The most complex and functional brain is considered to be a reasonable human brain.
The average mass of the brain in various living beings is given in the table.
The brain is enclosed in a solid shell of the skull (with the exception of simple organisms). In addition, it is covered with shells (lat. Meninges) of connective tissue - hard (lat. Dura mater) and soft (lat. Pia mater), between which there is a vascular, or arachnoid (lat. Arachnoidea) shell. Between the membranes and the surface of the brain and spinal cord is cerebrospinal (often called spinal) fluid - cerebrospinal fluid. Cerebrospinal fluid is also found in the ventricles of the brain. The excess of this fluid is called hydrocephalus. Hydrocephalus is congenital (more often) and acquired.
The brain of higher vertebrate organisms consists of a number of structures: the cerebral cortex, the basal ganglia, the thalamus, the cerebellum, the brainstem. These structures are interconnected by nerve fibers (pathways). The part of the brain, consisting mainly of cells, is called gray matter, of nerve fibers - white matter. White is the color of myelin, a substance that covers fibers. Demyelination of fibers leads to severe abnormalities in the brain (multiple sclerosis).
