They are not particularly vulnerable to injury because of their location at the back of the brain, although any significant trauma to the brain could produce subtle changes to our visual-perceptual system, such as visual field defects and scotomas.he occipital lobes are the center of our visual perception system.

Occipital Neuralgia View is from back of skull. Occipital neuralgia is usually due to trauma to the occipital nerve (ON), often caused by an auto-accident where the head impacts the headrest. Other causes are spondylosis of the upper cervical spine (C1-C2), or rarely focal neuropathies due to diabetes or tumor (Ehni and Benner, 1984).

Occipital bone Like the other cranial bones it is classed as a flat bone. Due to its many attachments and features the occipital bone is described in terms of separate parts. From its front to the back is the basilar part, at the sides of the foramen magnum are the lateral parts, and the back is named as the squamous part.

The Comprehensive Stroke Center at University Hospital Occipital Lobe - Region in the back of the brain which processes visual information. Not only is the occipital lobe mainly responsible for visual reception, it also contains association areas that help in the visual recognition of shapes and colors. Damage to this lobe can cause visual deficits.

The Effects of an Occipital Lobe Stroke A stroke affecting the left occipital lobe of the brain would cause a stroke survivor to have difficulty seeing objects on the right side. This problem typically affects both eyes- meaning that a person cannot see the right side from the right eye and also cannot see the right side from the left eye.

Occipital Neuralgia Occipital Neuralgia may occur spontaneously, or as the result of a pinched nerve root in the neck (from arthritis, for example), or as the result of prior injury or surgery to the scalp or skull. Sometimes “tight” muscles at the back of the head can entrap the nerves.

Brain Structure and Function Occipital Lobes. The occipital lobes are the location of the primary visual cortex and the visual association areas. Injury or lesions to the primary visual cortex cause vision impairments such as blindness or blind spots in visual fields. Damage to the association area can cause difficulties including visual distortions (aka agnosias) and visual inattention.

Occipital Lobe: Definition, Location & Function Location and Function of the Occipital Lobe. The occipital lobe is located in the posterior (back region) of the cerebrum, superior to (above) the cerebellum. It's protected by cranial bones, with the primary protective bone being the occipital bone. The occipital lobe is also divided into right and left halves, as is the entire cerebrum.

The Effects of an Occipital Lobe Stroke An occipital lobe stroke is a stroke that affects the back of the brain. The occipital lobe is the area of the brain that integrates our vision, allowing us to recognize and make sense of what our eyes see. In general, occipital lobe stroke are not common.

Occipital bone Occipital Bone. Sections. The occipital bone is part of the skull. It is located in the back of the head, directly above the neck. The occipital bone is one of eight fused bones that surround the brain, the meninges (the triple-layer membrane encasing the brain and spinal cord) and the cerebrospinal fluid.

Malpresentations and Malpositions Usually the fetal head engages in the occipito-anterior position (more often left occipito-anterior (LOA) rather than right) and then undergoes a short rotation to be directly occipito-anterior in the mid-cavity. Malpositions are abnormal positions of the vertex of the fetal head relative to the maternal pelvis.

The occipital lobe is at the back of the head, just above the neck.This is the primary projection area for vision.

Menkes syndrome Occipital horn syndrome (sometimes called X-linked cutis laxa) is a less severe form of Menkes syndrome that begins in early to middle childhood. It is characterized by wedge-shaped calcium deposits in a bone at the base of the skull (the occipital bone), coarse hair, and loose skin and joints.

Occipital Lobes and Visual Perception The occipital lobes are one of the four main lobes or regions of the cerebral cortex. These lobes are vital for receiving, processing, and interpreting sensory information. The occipital lobes are positioned at the posterior region of the cerebral cortex and are the main centers for visual processing. In addition to the occipital lobes, posterior portions of the parietal lobes and temporal lobes are also involved in visual perception.

Occipital lobe Occipital lobe. The occipital lobe is located at the rear portion of the skull, behind the parietal and temporal lobes. One of the most important parts of this lobe is the primary visual cortex, a region of the brain that receives input from the retina of the eye. This is where the mind interprets color and other important aspects of vision. The occipital lobe contains different areas pertaining to visual communication.

- Occipital neuralgia is the result of compression or irritation of the occipital nerves due to injury, entrapment of the nerves, or inflammation. Many times, no cause is found. There are many medical conditions that are associated with occipital neuralgia, including: 1  Trauma to the back of the head. 2  Neck tension and/or tight neck muscles. 3  Osteoarthritis. 4  Tumors in the neck.
