Two somatosensory projection areas, S I and S II, have been shown to exist in the brains of mammals of various species.3 S I, located in the postcentral gyrus, is especially concerned with the integration of sensory experience and with the discriminative qualities of sensation. S II has been mapped to the parietal operculum in many animal species,3 including humans.4 According to recent studies...

OBJECTIVE To investigate the importance of sufficient dissection of the interhemispheric and sylvian fissures, an orbitocranial approach was used for clipping of ruptured anterior communicating artery aneurysms. PATIENTS AND METHODS From January 1998 through March 2009, 41 patients underwent surgery for subarachnoid hemorrhage caused by rupture of an anterior communicating artery aneurysm. Th...

OBJECT The treatment of complex cerebrovascular or skull base pathological conditions necessitates a microsurgical blood flow preservation or augmentative revascularization procedure as either an adjunctive safety measure or a definitive treatment. The brain is susceptible to ischemia, and procedure-related risks can be minimized by the reduction of occlusion time or the use of a nonocclusive t...

BACKGROUND AND PURPOSE Despite the abundance of emerging multimodal imaging techniques in the field of stroke, there is a paucity of data demonstrating a strong correlation between imaging findings and clinical outcome. This study explored how proximal arterial occlusions alter flow in collateral vessels and whether occlusion or extent of collaterals correlates with prehospital symptoms of fluc...

OBJECTIVES One of the most commonly used eponymous terms in neuroscience and gross anatomy is Sylvius. The 2 most recognized uses of this term today are the sylvian fissure for the lateral cerebral sulcus and the sylvian aqueduct for the cerebral aqueduct. There is some controversy surrounding these terms because there were 2 famous anatomists named Sylvius after whom these structures could eas...

We examined 40 patients with ruptured middle cerebral aneurysms showing local symptoms in the brain as well as disturbance of consciousness. The overall mortality of those 40 cases was 27.5%. This was much lower than the mortality of 44.4% for cases with ruptured aneurysms of Hunt and Kosnik Grade IV which we also observed at approximately the sane time. The 40 cases consisted of 29 patients wh...
