| congenital cerebral aneurysm | Localised dilation of a cerebral vessel; usually a berry aneurysm. (05 Mar 2000) |
| plexiform layer of cerebral cortex | Layer 1 of the cortex cerebri. Synonym: plexiform layer of cerebral cortex. (05 Mar 2000) |
| plexus of anterior cerebral artery | <anatomy, artery> An autonomic plexus accompanying the anterior cerebral artery, derived from the internal carotid plexus. Synonym: plexus arteriae cerebri anterioris. (05 Mar 2000) |
| plexus of middle cerebral artery | <anatomy, artery> An autonomic plexus accompanying the middle cerebral artery, derived from the internal carotid plexus. Synonym: plexus arteriae cerebri mediae. (05 Mar 2000) |
| cortical part of middle cerebral artery | <anatomy, artery> See: middle cerebral artery. Synonym: pars corticalis arteriae cerebralis mediae. (05 Mar 2000) |
| postcommunical part of anterior cerebral artery | <anatomy, artery> The continuation of the anterior cerebral artery after the anterior communicating artery; it supplies branches to the cerebral cortex as it passes along the corpus callosum. Synonym: pars postcommunicalis arteria cerebri anterior, arteria pericallosa, postcommunical part of anterior cerebral artery. (05 Mar 2000) |
| posterior branch of lateral cerebral sulcus | The long, posteriorly-directed continuation of the lateral cerebral sulcus which extends between the temporal lobe inferiorly and the parietal lobe superiorly, its termination surrounded by the supramarginal gyrus. Synonym: ramus posterior sulci lateralis cerebri. (05 Mar 2000) |
| posterior cerebral artery | <anatomy, artery> Formed by the bifurcation of the basilar artery; it passes around the cerebral peduncle to reach the medial aspect of the hemisphere; for descriptive purposes it is divided into three parts: 1) the precommunical part (P1 segment of clinical terminology), the part before the junction with the posterior communicating artery, supplying parts of the thalamus, hypothalamus, and midbrain; 2) the postcommunical part (P2), supplying the thalamus, cerebral peduncles, and the choroid plexuses of the lateral and third ventricles; and 3) the terminal or cortical part, supplying the cortex of the temporal (P3) and occipital (P4) lobes. Synonym: arteria cerebri posterior. (05 Mar 2000) |
| posterior cerebral commissure | A thin band of white matter, crossing from side to side beneath the habenula of the pineal body and over the aditus ad aqueductum cerebri; it is largely composed of fibres interconnecting the left and right pretectal region and related cell groups of the midbrain; dorsally, it marks the junction of the diencephalon and mesencephalon. Synonym: posterior cerebral commissure. (05 Mar 2000) |
| precommunical part of anterior cerebral artery | precommunical part of anterior cerebral artery |
| progressive cerebral poliodystrophy | Familial progressive spastic paresis of extremities with progressive mental deterioration, with development of seizures, blindness and deafness, beginning during the first year of life, and with destruction and disorganization of nerve cells of the cerebral cortex. Synonym: Alpers disease, Christensen-Krabbe disease, progressive cerebral poliodystrophy. (05 Mar 2000) |
| progressive circumscribed cerebral atrophy | Circumscribed atrophy of the cerebral cortex. Synonym: lobar sclerosis, progressive circumscribed cerebral atrophy. (05 Mar 2000) |
| high altitude cerebral oedema | <physiology> A serious condition that results from the sudden increase in pressure within the brain due to swelling. This is thought to occur secondary to exposure to high altitudes, generally in excess of 12,000 feet. (12 Jan 1998) |
