What does the left lingual gyrus do?
The lingual gyrus, also known as the medial occipitotemporal gyrus, is a brain structure that is linked to processing vision, especially related to letters. It is thought to also play a role in analysis of logical conditions (i.e., logical order of events) and encoding visual memories.
What does the cuneus do in the brain?
It is a smaller lobe in the occipital lobe of the brain. The cuneus (Brodmann area 17) receives visual information from the contralateral superior retina representing the inferior visual field. It is most known for its involvement in basic visual processing.
What is the lingual gyrus?
The lingual gyrus is a tongue-shaped structure that lies on the medial aspect of the occipital lobe along the inferomedial (tentorial) surface 1.
What separates the cuneus and lingual gyrus?
An important landmark on the medial aspect of the occipital lobe is the calcarine sulcus. This sulcus separates the cuneus, which is superior to it, from the lingual gyrus, which is inferiorly located.
Where is lingual gyrus located?
occipital lobe
The lingual gyrus is a tongue-shaped structure that lies on the medial aspect of the occipital lobe along the inferomedial (tentorial) surface 1.
Which artery supplies blood to the lingual gyrus?
calcarine artery
Blood supply The lingual gyrus is supplied largely by the calcarine artery, but can also receive blood from the lingual gyrus artery, posterior temporal artery and common temporal artery in a proportion of people (8.3%, 60% and 28.4% respectively in one study) 3.

What happens if the angular gyrus is damaged?
Lesions causing damage to the angular gyrus can give rise to a constellation of symptoms. The classic symptoms include alexia with agraphia, constructional disturbances with or without Gerstmann’s tetrad and behavioural manifestations such as depression, poor memory, frustration and belligerence.
What can damage the insular cortex?
Addiction and other conscious desires. Thus damage to the cingular cortex may alter behavior, particularly compulsive behaviors such as shopping or gambling. Interoceptive awareness—your ability to be consciously aware of bodily states, such as heart beat.
What is the function of the lingual gyrus?
(Lingual gyrus visible at right.) The lingual gyrus, also known as the medial occipitotemporal gyrus, is a brain structure that is linked to processing vision, especially related to letters. It is thought to also play a role in analysis of logical conditions (i.e., logical order of events) and encoding visual memories.
Where is the lingual gyrus of the occipital lobe?
Location The lingual gyrus of the occipital lobe lies between the calcarine sulcus and the posterior part of the collateral sulcus; behind, it reaches the occipital pole; in front, it is continued on to the tentorial surface of the temporal lobe, and joins the parahippocampal gyrus.
Is the lingual gyrus associated with visual snow?
Contrary to the name, the region has little to do with speech. It is believed that a hypermetabolism of the lingual gyrus is associated with visual snow.
How is the cuneus separated from the parietal lobe?
Anterosuperiorly the parieto-occipital sulcus separates the cuneus from the precuneus of the parietal lobe. Posteroinferiorly the cuneus abuts the calcarine sulcus which separates it from the lingual gyrus 1.
