Function: Responsible for processing visual information from the eyes such as What happens if the occipital lobe gets damaged? Injury to the occipital lobes may lead to vision impairments such as blindness or blind spots; visual distortions and visual inattention. The occipital lobes are also associated with various behaviors and functions that include: visual recognition; visual attention; and spatial analysis. The primary visual cortex is the most studied visual area in the brain. These lesions may sometimes lack cortical representation and only manifest as an arterialized vein on the surface. Its positioned at the back of both brain hemispheres, They included visual areas V1, V2 and V5/MT, lingual, fusiform, superior, middle and inferior occipital gyri, occipital pole and cuneus.

The occipital lobes sit at the back of the head and are responsible for visual perception, including colour, form and motion. Diagn Interv Radiol. The skull bones separate facial structures from the brain.
While several studies tested this network recently, its relationship to the lateral occipital (LO) cortex known to be involved in visual object perception remains largely unknown. What does calcarine sulcus separate? Lateral parieto-occipital AVMs are typical cone-shape convexity AVMs. Posteriorly, it separates the lingula and occipitotemporal gyrus, and anteriorly, it courses between the parahippocampal and the occipitotemporal gyri. This includes projections with the temporal pole, perirhinal cortex, parahippocampal cortex itself (i.e., TF projects to TH). The direction of the fissure varies, but it is usually horizontal, and it joins the parieto-occipital fissure anteriorly and achieves a varying distance toward or further (and onto the lateral part) of the occipital pole.

The occipital craniotomy is designed to provide operative exposure of the occipital lobe, tentorium and posterior incisural space, splenium of the corpus callosum, medial and posterior In mammals, it is located in the posterior pole of the occipital lobe and is the simplest, earliest cortical visual area. The blind spot will be on the same side as the stroke. However the exact localization of the epileptic focus sometimes represents a problem because of the rapid propagation to frontal, parietal, or temporal regions. Quick facts: Location: Bottom, back part of the cortex above the cerebellum and behind the temporal lobe. Occipital Lobe ( lobus occipitalis ).
