The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 cm in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure ...
The parietal-temporal-occipital (PTO) association area, also referred to as the temporo-parieto-occipital (TPO) junction, is an area within the cerebral cortex where the parietal, temporal and occipital lobes meet. [1] High level of interpreting meaningful signals in the surrounding sensory area. They have functional subareas:
The P2 component, also known as the P200, is so named because it is a positive going electrical potential that peaks at about 200 milliseconds (varying between about 150 and 275 ms) after the onset of some external stimulus. This component is often distributed around the centro-frontal and the parieto-occipital areas of the scalp.
It can also refer to the occipital operculum, part of the occipital lobe. The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus. It sits like an island (the meaning of insular) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.
Therefore, he further modified his surgery to functionally sever residual portions of the frontal and parieto-occipital lobes. [4] This surgery, the functional hemispherectomy, has been further modified over the years by several different neurosurgeons, and to this day there is not a consensus as to which exact technique should be used.
[60] There are documented cases of reversible frontotemporal dementia and coma. [61] Coma due to a CSF leak has been successfully treated by using blood patches and/or fibrin glue and placing the person in the Trendelenburg position. [62] Empty sella syndrome, a bony structure that surround the pituitary gland, occurs in CSF leak patients. [46 ...

The syndrome features acute neurological symptoms and reversible subcortical vasogenic edema predominantly involving the parieto-occipital areas on MR imaging. [28] PRES in general has a benign course, but PRES-related intracranial hemorrhage has been associated with a poor prognosis. [29]
