The lingual gyrus, also known as the medial occipitotemporal gyrus, [1] 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.
Anton syndrome, also known as Anton-Babinski syndrome and visual anosognosia, is a rare symptom of brain damage occurring in the occipital lobe.Those who have it are cortically blind, but affirm, often quite adamantly and in the face of clear evidence of their blindness, that they are capable of seeing.
Sagittal MRI slice with the precuneus shown in red. (Anterior to the left.) ... It is located in front of the cuneus (the upper portion of the occipital lobe).
Posterior reversible encephalopathy syndrome; Other names: Reversible posterior leukoencephalopathy syndrome (RPLS) Posterior reversible encephalopathy syndrome visible on magnetic resonance imaging as multiple cortico-subcortical areas of T2-weighted hyperintense (white) signal involving the occipital and parietal lobes bilaterally and pons.
The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The name derives from its position at the back of the head, from the Latin ob, 'behind', and caput, 'head'. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. [1]
Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.

The occipital gyri (OcG) are three gyri in parallel, along the lateral portion of the occipital lobe, also referred to as a composite structure in the brain. [1] [2] The gyri are the superior occipital gyrus, the middle occipital gyrus, and the inferior occipital gyrus, and these are also known as the occipital face area. [1]
The cuneus (from Latin 'wedge'; pl.: cunei) is a smaller lobe in the occipital lobe of the brain. The cuneus is bounded anteriorly by the parieto-occipital sulcus and inferiorly by the calcarine sulcus.
