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]
Occipital lobe epilepsy is fairly rare, and may sometimes be misdiagnosed as migraine when symptomatic. Epileptic seizures are the result of synchronized neural activity that is excessive, and may stem from a failure of inhibitory neurons to regulate properly. [1] It is a disorder with focal seizures in the occipital lobe of the brain.
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.
Idiopathic childhood occipital epilepsy of Gastaut (ICOE-G) is a pure but rare form of idiopathic occipital epilepsy that affects otherwise normal children and adolescents. [1] It is classified amongst benign idiopathic childhood focal epilepsies such as rolandic epilepsy and Panayiotopoulos syndrome .
Diagram of gyri of brain viewed on lateral hemisphere. Occipital gyri shown lower right. The border between the occipital lobe and the parietal and temporal lobes is characterized by different gyri: the superior occipital gyrus (also known as gyrus occipitalis superior), middle occipital gyrus (or gyrus occipitalis medius), inferior occipital gyrus (or gyrus occipitalis inferior), and ...
Analyzing variability in the location of gross anatomical landmarks such as sulci is an accepted method for studying evolutionary hominin brain reorganization. The position of the lunate sulcus in the occipital lobe has been studied in humans, early hominin endocasts, apes, and monkeys by researchers seeking to make inferences about the morphological evolution of brain regions associated with ...
The results of the study support the idea that serotonin damage due to MDMA use causes lateral inhibition to diminish amongst orientation sensitive neurons in the occipital lobe. [3] This was demonstrated by the Ecstasy group showing a greater increase in the magnitude of the TAE illusion compared to the controls. [ 3 ]
The occipital face area (OFA) is a region of the human cerebral cortex which is specialised for face perception. The OFA is located on the lateral surface of the occipital lobe adjacent to the inferior occipital gyrus . [ 1 ]
