Hemihypesthesia
Hemihypesthesia is a reduction in sensitivity on one side of the body. A person with this condition may not be able to perceive being lightly touched on one side, but has normal function on the other side of the body. It can occur from damage to the thalamocortical fibers in the posterior limb of the internal capsule. It is one of the deficits produced by anterior choroidal artery syndrome. The anterior choroidal artery is in the brain, off of the internal carotid in the "circle of Willis The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including huma ...".

Anterior Choroidal Artery Syndrome
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, ''Terminologia Anato ...
