Somatosensory Cortex in the Parietal Lobe

Localization and the Homunculus Man

The diagram reflects the relative space each body part occupies in the somatosensory cortex by reflecting organs that have high density of sensory receptors and nerves as large organs and those with a lesser sensory apparatus as small organs. Hence the mouth lips, hands feet and genitalia have a relatively large representation. The homunculus man (literally the “little man”) is the distorted figure drawn to reflect the concept of size of organ paralleling the size of the sensory innervation.

Michelangelo

God Like Figure painted in the form of a Brain?

 

This painting on the Sistine chapel by Michelangelo has such poignancy in its depiction of a moment in time with a focus on the fingers of God and Adam. If you cast your eye and open your mind to the image of God and angels you may perceive a sagittal section of the brain depicted as a background with God’s angels embedded in the “brain”

The C Rings

The forebrain has most of its components aligned in a series of inverted c- shaped rings starting from the outer membranes that culminate in the falx (pink), then extending inward smaller inner rings with each intimately connected to the others. The thalamus (dull orange) appears diagrammatically as the centre of these rings as seen from the sagittal view The outer ring is the falx (pink) followed by the sagittal sinus (blue) cerebral cortex (light green), cingulate gyrus (bright green) superiorly which becomes the parahippocampal gyrus inferiorly. The red ring represents the distribution of the main portion of the anterior cerebral artery. Next is the yellow ring which is the supracollosal gyrus (indusium griseum) superiorly and the hippocampus inferiorly. This is followed by the corpus callosum (purple) which enables the white ring of white matter to connect between hemispheres. The next ring is the thin bright pink ring which represents the fornix superiorly and the fimbria inferiorly. The innermost ring (light blue) represents the lateral horns of the ventricular system. The basal ganglia run just lateral to the lateral ventricles. The navy blue arrow headed structure is the septum pellucidum.

The Circle of Willis (COW)

The cerebral circulation has a unique system that allows for compensatory flow when any one of the 4 vessels is narrowed or occluded. This cerebral circulation is centered on the circle of Willis which has two basic systems that feed it; the carotid system (in this case salmon pink) and the vertebro-basilar system (brighter pink). They both feed into the circle of Willis (bright red) via communicating branches. The middle cerebral artery is the vessel that feeds into the COW by providing the anterior communicating artery and the posterior cerebral artery connects via the posterior communicating artery. Conceptually as depicted in this diagram the circle of Willis is the centre of the cerebral circulation and from it blood flows into the anterior (bright green), middle (darker green) and posterior cerebral (maroon) regions.

The Red Brain?

The color red reflects an inflammed emotion or an inflammed body so that in the emotional world it may reflect rage and the physical world may reflect a fever in general or an inflammation of the brain
