Superior sagittal sinus, the largest dural venous sinus, runs in sagittal plane and drains most of the blood from the surface of both cerebral hemispheres. It also receives blood from diploic, meningeal and emissary veins.
[22,23] Schizencephaly, which is a rare congenital (present from birth) brain malformation, in which abnormal slits or clefts form in the cerebral hemispheres of the brain was noted in 1 patient.
A team of university professors in Japan examined the links between brain structure and happiness and found that happier people had a larger volume of grey matter in the precuneus, an area in the brain sandwiched between the two cerebral hemispheres that studies have linked to memory retrieval.
Medical device company Cerebrotech Medical Systems stated on Friday that it has passed US Food and Drug Administration (US FDA) clearance for the Cerebrotech Visor for use as an aid in the assessment of fluid volume differences between the cerebral hemispheres in patients undergoing neurologic assessment.
(ii) A second set of VOIs was automatically generated in the cortex and the striatum by using the regions proposed by the PMOD rat brain template, to study the evolution of [[sup.18]F]FDG PET signal in these specific regions in both the ipsilateral and contralateral cerebral hemispheres. PET signal uptake was averaged in each ROI and expressed as percentage of injected dose per cubic centimetre (%ID/cc), and the hemispheres ratios were considered.
