She developed seizures since 2 years old and electroencephalography showed paroxysmal activities on the left occipital area. At 8 years old, partial resection of the lesion and interictal spike focus under intraoperative corticography guidance was performed, but the favorable seizure outcome was not obtained. At the age of 20 years old, the frequency of her seizures has increased and admitted to our department. Preoperative evaluation with chronic invasive subdural recording showed that the ictal zone was located in the inferior (tentorial) surface and convexity of ...

Brodmann area 19, or BA 19, is part of the occipital lobe cortex in the human brain. Along with area 18, it comprises the extrastriate (or peristriate) cortex. In humans with normal sight, extrastriate cortex is a visual association area, with feature-extracting, shape recognition, attentional, and multimodal integrating functions. This area is also known as peristriate area 19, and it refers to a subdivision of the cytoarchitecturally defined occipital region of cerebral cortex. In the human it is located in parts of the lingual gyrus, the cuneus, the lateral occipital gyrus (H) and the superior occipital gyrus (H) of the occipital lobe where it is bounded approximately by the parieto-occipital sulcus. It is bounded on one side by the parastriate area 18, which it surrounds. It is bounded rostrally by the angular area 39 (H) and the occipitotemporal area 37 (H) (Brodmann-1909). Brodmann area 19-1909 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. ...

Strokes that affect one or both occipital lobes of the brain result in visual deficits. Occipital lobe strokes are relatively uncommon.
The calcarine fissure (or calcarine sulcus) is an anatomical landmark located at the caudal end of the medial surface of the brain. Its name comes from the Latin calcar meaning spur.. It is a complete sulcus. The calcarine sulcus begins near the occipital pole in two converging rami and runs forward to a point a little below the splenium of the corpus callosum, where it is joined at an acute angle by the medial part of the parietooccipital sulcus. The anterior part of this fissure gives rise to the prominence of the calcar avis in the posterior cornu of the lateral ventricle. The calcarine sulcus is where the primary visual cortex (V1) is concentrated. The central visual field is located in the posterior portion of the calcarine sulcus and the peripheral visual field in the anterior portion. ...
The term parieto-occipital sulcus refers to the groove in the cerebral cortex that separates the precuneus of the parietal lobe from the cuneus of the occipital lobe on the medial surface of the cerebral hemisphere. It is found in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). In the macaque it merges with the intraparietal sulcus, and the lunate sulcus of the macaque on the dorsal surface of the brain ( Kappers-1960 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). ...
The clinical evidences of variable epileptic propagation in occipital lobe epilepsy (OLE) have been demonstrated by several studies. However the exact localization of the epileptic focus sometimes represents a problem because of the rapid propagation to frontal, parietal, or temporal regions. Each white matter pathway close to the supposed initial focus can lead the propagation towards a specific direction, explaining the variable semiology of these rare epilepsy syndromes. Some new insights in occipital white matter anatomy are herein described by means of white matter dissection and compared to the classical epileptic patterns, mostly based on the central position of the primary visual cortex. The dissections showed a complex white matter architecture composed by vertical and longitudinal bundles, which are closely interconnected and segregated and are able to support specific high order functions with parallel bidirectional propagation of the electric signal. The same sublobar lesions may ...

Strip. There is currently a large debate between these two and this FAQ is not meant to foster this debate, only to present the facts. I see the following as risks of Strip Excision and benefits of FUE. With strip excision a strip of flesh is removed from the permanent ring of hair around the occipital lobe and sides of the head. The most serious problem that occurs is excessive scarring, because the remaining tissue cannot accommodate the tissue that has now been depleted, and over time stretches. To demonstrate. Lean your head forward until your chin is touching your chest. Place your hand firmly on your occipital lobe near the base of your head. Pinch this area of skin. Any where from a few millimeters to an entire inch of skin may be removed from this pliant skin. This loose skin gives us what is known as laxity. Which allows you to comfortably move your head and sleep. Do not trust anyones opinion other than your own if you have enough laxity to spare for this surgery. Perform the same ...
Lets first try to plot some of these data. Suppose we take a smaller fraction of the entire dataset. You can find a fragment of 21 rows and 3 columns of measurements here. This number is large enough to require computer software to graph the data. In column 1, this data subset includes an index of the region (blob) and in column 2, a pair of MEAN & Standard Deviation for the intensities over the blob (within the Left Occipital lobe). Now go to SOCR Charts and select the StatisticalBarChardDemo1 Chart (under BarCharts --, CategoryPlot), see figure below). Clear the default data and Paste in this data segment. Map the first column (C1) to Series and the second column (C2) to Categories and click UPDATE to redraw the graph with the new data. This plot shows the relations between the means and standard deviations of the intensities in the 21 regions (blobs, rows in table). We see that there is variation in both means and standard deviations (error bars on the box plots). ...

The current study demonstrates relationships among cerebral hemodynamics, obesity, and cognition. In older men with CAD, microvascular ATT decreased in association with obesity and poorer cognitive function. The implicated regions included areas of the lateral occipital, precuneus, angular gyrus, middle temporal, and frontal pole. In addition, the macrovascular LATT was significantly associated with hypertension, but not with obesity.. ATT differences associated with obesity occurred primarily in the parietal and occipital lobes. This result is notable for a few reasons. First, the regions identified are consistent with the default mode network, which is a network implicated in cognitive function in later life.33,34 Second, precuneus ATT was also found to be negatively associated with cognitive function. Third, ATT in brain regions identified by obesity explained 21% of the variance in cognitive function across the group.. The pressor component was defined by SBP and pulse pressure; however, it ...

In brain anatomy, the lunate sulcus or simian sulcus also known as the sulcus lunatus is a fissure in the occipital lobe found in humans and more often larger when present in apes and monkeys. The lunate sulcus lies further back of human brains but has a more frontal location in chimpanzees. The evolutionary expansion of the frontal areas of the lunate sulcus would have caused a shift in the particular location of the fissure. It has been hypothesized that evolutionary pressures resulted in the human brain undergoing internal reorganization to develop the capability of human language. Furthermore, this reorganization must have been implemented during early maturity and is likely responsible for eidetic imagery in some adolescents. During early development, the neural connections in prefrontal cortex and posterior parietal lobe rapidly expand to allow capability for human language, while visual memory capacity of human brain would become limited. Biological studies have demonstrated that the ...

The term superior parietal lobule refers to one of four subdivisions of the parietal lobe identified by dissection in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). Located on the dorsal margin of the cerebral hemisphere, it is, in the human, separated rostrally from the postcentral gyrus by the postcentral sulcus and a line extending from the upper end of that sulcus over the margin of the cerebral hemisphere to the cingulate sulcus, which separates it from the cingulate gyrus. Thus, it includes the caudal portion of the paracentral lobule. Caudally its boundary with the occipital lobe is an oblique plane through the parieto-occipital sulcus on the dorsomedial margin of the hemisphere and the preoccipital notch on the ventromedial margin.. Its boundary on the dorsolateral surface of the hemisphere is the intraparietal sulcus, which separates it from the supramarginal gyrus and the angular gyrus of the inferior parietal lobule. The other three parts of the parietal lobe are the ...

Many neuroimaging studies have demonstrated the different functional contributions of spatially distinct brain areas to working memory (WM) subsystems in cognitive tasks that demand both local information processing and interregional coordination. In WM cognitive task paradigms employing electroencephalography (EEG), brain rhythms such as θ and α have been linked to specific functional roles over given brain areas, but their functional coupling has not been extensively studied. Here we analyzed an arithmetic task with five cognitive workload levels (CWLs) and demonstrated functional/effective coupling between the two WM subsystems: the central executive located over frontal (F) brain areas that oscillates on the dominant θ rhythm (Frontalθ/Fθ) and the storage buffer located over parieto-occipital (PO) brain areas that operates on the α2 dominant brain rhythm (Parieto-Occipitalα2/POα2). We focused on important differences between and within WM subsystems in relation to behavioral ...
60 MORPHOLOGY AND BVOLDTION sulcus. Above the insula there lies a short inferior transverse sulcus (I.T.S.) The calcarine (Ca.S.) and retro-calcarine sulei are continuous, and the collateral sulcus (Co.S.) is simple. The calloso-marginal (C-JI.S.) sulcus is well marked, but the parieto-occipital sulcus is variable. The olfactory apparatus is small (microsmatism), and the cerebellum appears to be small. The flocculus is smaller than the paraflocculus, which forms the petrosal lobule. The trapezium is not concealed. The brain is small in some of the Baboons, and its degree of convolution varies in different Cercopithecidae. The visual area of the neopallium (i.e., all the cerebral cortex apart from the olfactory areas is well developed, and it is more complex than in Tarsius. The eyes have maculae luteae and there is an incomplete optic decussation. So the Cercopithecidse, like the Cebidse, have the complete apparatus for binocular stereoscopic vision. Moreover the tactile sense lodged in the ...
Question - Had fracture of right occipital. On vertin for vertigo. Feeling giddiness and weakness. What precaution should be taken?. Ask a Doctor about diagnosis, treatment and medication for Vertigo, Ask a Neurologist
In the present experiments, we analyzed the cortical thickness of left and right ventral occipitotemporal regions. We refined traditional analyses by applying a subject-by-subject functionally based approach and measured the structural properties of individually defined functional territories. We found a cortical thickness reduction in dyslexic children, specifically located around the response peak to words in the left hemisphere; furthermore, the global group difference was carried exclusively by girls. These results were replicated in two independent datasets of dyslexic and control children, whereas no consistent difference was observed around the functional peaks of other visual categories (houses and faces).. A reduction of gray matter tissue across occipitotemporal regions in dyslexia has been inconsistently reported. Although increased gray matter volume was observed in the left fusiform gyrus of dyslexic subjects by Silani et al. (2005), the opposite effect was subsequently described ...

And finally I received a long awaited call from our pediatric genetics office about several tests we are doing with William in our search for a specific diagnosis. Our doctor already tested for hundreds of more common syndromes and completed a micro-ray analysis which shows that his chromosomes are typical. Of course we know via MRI that his brain is not typical; he is missing a lot of tissue in the center and the occipital lobe is smooth versus a normal brain which has ridges and folds. These last few tests were for more rare syndromes and ALL come back negative. We may have one lead; a blood test showed elevated protein levels. I am taking him in to get another blood draw next week for a re-test and then testing for some metabolic disorders. I spoke briefly with a genetics counselor over the phone who told me high protein levels could simply mean he ate to much chicken or his body is missing some enzymes that break down proteins and high levels could be toxic to the brain....hmmmmm... I hung ...
I take no issues with premiss (i), the other premisses are the ones which I take issue with. What I got from (ii) was that some immaterial world is responsible for deciphering outer light into an image that can be seen, I take this to refer to visual processing, this is plainly wrong, the occipital lobe is responsible for visual processing and not an immaterial world within a human being. It also propounds the existence of a substance dualism between body and mind, even though this is highly disregarded within neuroscience. With point (iii), I cant manage to understand what exactly its trying to establish, since there is no immaterial world which we have experienced. Of course, if (iv) was meant to be the conclusion, then it is not consequent upon the premisses and thus is invalid. If it was just another point, then I mean, what else can I say apart from I have no evidence for believing that I am an eternal spirit, when there is evidence to the contrary ...
