Cuneus
Cuneus
Cuneus (pronounced: kyu-nee-us) is a small region of the brain located in the occipital lobe, the part of the brain responsible for processing visual information. The term "cuneus" is derived from the Latin word for "wedge," reflecting the shape of this brain region.
Function
The cuneus is primarily involved in basic visual processing and has been linked to functions such as spatial orientation, color discrimination, and motion perception. It receives visual information from the retina of the eye and sends this information to other areas of the brain for further processing.
Anatomy
The cuneus is located in the medial part of the occipital lobe, bordered by the calcarine sulcus inferiorly and the parieto-occipital sulcus anteriorly. It is surrounded by other important brain regions involved in visual processing, including the lingual gyrus and the precuneus.
Clinical Significance
Damage to the cuneus can result in visual disturbances, such as hemianopia (loss of half of the visual field) or cortical blindness (loss of vision caused by damage to the brain's occipital cortex). It has also been implicated in conditions such as migraine and epilepsy.
