What is Sylvian fissure in brain?
The Sylvian fissure can be identified at 12 to 14 weeks of gestation as shallow depression on the lateral surface of the brain. It is formed by the convergence of the frontal, parietal, and temporal lobes over the insula.
What is insular infarct?
Abstract. Infarction of the insula is a common scenario with large tissue-volume strokes in the middle cerebral artery territory. Considered to be part of the central autonomic network, infarction of this region is associated with autonomic disturbances, in particular cardiovascular dysregulation.
What does the middle cerebral artery affect?
The primary function of the MCA is to supply specific regions of brain parenchyma with oxygenated blood. The cortical branches of the MCA irrigate the brain parenchyma of the primary motor and somatosensory cortical areas of the face, trunk and upper limbs, apart from the insular and auditory cortex.
What is cerebral occlusion?
Overview. When an artery inside the skull becomes blocked by plaque or disease, it is called cerebral artery stenosis. Arteries anywhere in the body can become blocked. For example, carotid artery stenosis is a narrowing of the large artery in the neck, the carotid, that supplies oxygen-rich blood to the brain.
When does the Sylvian fissure develop?
The Sylvian fissure, the deepest sulcus on the lateral hemispheric surface, can be identified as early as 12 weeks of gestation and serves as a major landmark for the dynamic changes of the brain surface.
Where is my Sylvian fissure?
The Sylvian Fissure: It is easy to identify, moving across the brain from the bottom toward the top as following an antero–posterior course. Its start marks the limit between the temporal pole and the frontal lobe, and, after an uninterrupted course, it ends posteriorly with a bifurcation into two sulci.
What is the insula brain?
The insula (or insular cortex) is a thin ribbon of gray matter tissue that lies just deep to the lateral brain surface, separating the temporal lobe from the inferior parietal cortex.
What happens when the insular cortex is damaged?
In case of damage to the insula, people will have difficulties with sensory perceptions. For instance there is a possibility that they won’t be able to differentiate and feel touch. Damage to insula mean people won’t be able to taste and smell anything. We are aware of our body because of insular cortex.
What does infarctus mean in French?
infarctus [le ~] noun. l’infarctus (crise cardiaque; infarctus du myocarde; paralysie cardiaque) the heart attack – a sudden severe instance of abnormal heart function 1. heart attack [the ~] noun. the heart failure – inability of the heart to pump enough blood to sustain normal bodily functions 1.
What are the types of infarctus?

Which infarctus is considered a surgical emergency?
L’ infarctus mésentérique et la péritonite aiguë sont également des urgences chirurgicales. The mesenteric infarction and acute peritonitis are also surgical emergencies. Les embolies pulmonaires périphériques de moindre envergure peuvent provoquer un infarctus pulmonaire.
What does Sylvian mean in medical terms?
