The Brain

The brain is the most complex organ in the body, and the approach to understanding its structure must evolve from its most basic form that will stand as a foundation to the advancing complexity. As such one approach to understanding its structure, is to start with stick diagrams that draw simple intuitive lines of the vectors or axes of the brain, in an attempt to conceptualize the many parts of the brain and how they fit together.
Looking at the brain from its lateral aspect is very different from looking at it from above or from front. The sectional views in sagital axial and coronal projections add even more complexity as the vista of the structures changes every few mms. Even with this method it is difficult to understand brain structure because one has to conceptualize these vectors from many angles.
We will start by providing simple conceptual diagrams of the brain from the side, from above and from the front
The Basic Structure of the Brain from its Lateral Aspect – The brain at its simplest
The stick diagram divides the brain into a relatively long almost horizontal component, and a relatively short almost vertical component. Anatomically the horizontal component is called the forebrain, and the vertical component will make up the midbrain (orange) and hind brain (salmon) and extend into the spinal cord
Major Parts of the Brain
This artistic rendition of the brain reflects the vectors of the major parts of the brain with the stick diagram overlaid on a sagittal external view of the brain. In the stick diagram, the forebrain has now been divided into the frontal lobe (bright green), parietal lobe (light mauve) occipital lobe (purple) and temporal lobe (red). The midbrain is represented in orange, and the hind brain consists of the pons (pink) medulla (salmon) and the cerebellum (maroon)
The Flower of the Brain in Blue
A CTA (CT angiogram) of the brain is combined with an CTA of the carotid arteries to form the image of the flower of the brain.
BrainTree – Derivation
BrainTree is derived from an anatomical specimen of the brain. The forebrain has been artistically rendered to create the leaves and branches of the tree. The trunk and the roots extnd from the hind brain and the top of the spinal cord.
