Lingual gyrus
Lingual gyrus
The Lingual gyrus is part of the brain located in the occipital lobe, specifically on the underside of the brain. It is named for its proximity to the tongue, as "lingual" is derived from the Latin word "lingua," which means tongue. The Lingual gyrus is part of the visual cortex, which is responsible for processing visual information.
Etymology
The term "Lingual gyrus" comes from the Latin word "lingua," which means tongue. This is due to the gyrus's location near the tongue-shaped occipital lobe of the brain.
Anatomy
The Lingual gyrus is located between the calcarine sulcus and the collateral sulcus; it extends from the occipital pole to the occipitotemporal sulcus. It is part of the visual cortex, which is responsible for processing visual information.
Function
The Lingual gyrus plays a significant role in visual processing. It is involved in the processing of visual signals, the formation of memories related to visual input, and the recognition and identification of objects. It is also thought to play a role in dreaming and daydreaming.
Clinical significance
Damage to the Lingual gyrus can result in a variety of visual disorders, including visual agnosia, prosopagnosia, and hallucinations. It has also been associated with conditions such as schizophrenia and Alzheimer's disease.
