The vertebrobasilar system provides blood to the cerebellum, brain stem, occipital lobes
, and posterior portions of the temporal lobes and partially to the internal capsules, thalami, and basal ganglia.
In uncomplicated patients, magnetic resonance imaging (MRI) of the brain illustrates edema primarily in the cortex and subcortical white matter of posterior brain regions, such as the occipital lobes
and posterior parietal lobes.
There was a "readily discernible noteworthy gradient loss when moving from anterior to posterior regions," with the occipital lobes
in the back of the head responsible for vision being most severely affected.
The cortex of the brain is separated into the major lobes: frontal (decision-making), parietal (sensing pain and understanding speech), temporal (memory), occipital lobe
(eyesight), cerebellum (balance), and the thalamus (relay station connecting them all together).
They put a neural implant in the occipital lobe
of a blind volunteer.
On the other hand, similar clinical manifestations have been described, albeit rare, in patients with occipital lobe
An MRI of the infant's brain indicated severe cerebral abnormalities, including severe bilateral white-matter loss in the temporal and occipital lobe
, consistent with focal cerebral destruction.
Its contouring capability maximizes the surface area contact and cradles bony prominences, particularly in the heel and occipital lobe
Each hemisphere, in turn, is comprised of four sections, or lobes: frontal, temporal, parietal, and occipital lobe
My standard response is, "How many people come to a doctor and say, 'My ascending aorta is killing me,' or 'My occipital lobe
is bothering me'?
Such a chain is very aggressive and the likelihood of kickback is Don't attempt nose, cuts (plunge cuts) with this chain, and do not use it on a light chainsaw or it will likely kickback right through to your occipital lobe
In contrast, alexia without agraphia (which is associated with lesions to the left occipital lobe
and the splenium of the corpus callosum) was thought to arise from a disconnection of visual word form processing ( in the left angular gyrus) from visual processing in the occipital cortex.
However, the distribution of pathology is different to that of typical AD, (16) with PCA exhibiting higher plaque and tangle counts in the occipital lobe
and lower plaque and tangle counts in more anterior cortices than typical AD, consistent with the different patterns of brain shrinkage observed.
In this scan, the pulvinar communicates with the occipital lobe
and the temporal lobe individually, and with both.
19) The pattern of FDG metabolism in DLB differs from AD; in contrast to the classic appearance of bilateral temporal-parietal reductions in FDG metabolism with AD, DLB commonly appears as globally reduced cortical metabolism, most notably in the visual association cortex of the occipital lobe
