Pattern electroretinograms after cerebral hemispherectomy.
Cortically blind patients with brain damage restricted to the optic radiations or primary visual cortex may be able to detect and discriminate visual stimuli presented in their field defects, even though they deny seeing them. In contrast, patients who are hemianopic as a result of cerebral hemispherectomy cannot explicitly discriminate visual stimuli in their field defects, even when forced ch...
متن کاملCerebral Reorganization after Hemispherectomy: A DTI Study.
BACKGROUND AND PURPOSE Hemispherectomy is a neurosurgical procedure to treat children with intractable seizures. Postsurgical improvement of cognitive and behavioral functions is observed in children after hemispherectomy suggesting plastic reorganization of the brain. Our aim was to characterize changes in DTI scalars in WM tracts of the remaining hemisphere in children after hemispherectomy, ...
متن کاملPathophysiology of cerebral ischemia.
The purpose of this manuscript is to briefly review the pathophysiology of cerebral ischemia. Ischemic thresholds are well-defined in lower animals. The concept of the ischemic penumbra may include regions of brain around deeper regions of ischemia but has also been defined in terms of brain salvageable by reperfusion or by pharmacological therapies. The principal pathophysiological processes i...
متن کاملDichotic listening after cerebral hemispherectomy: methodological and theoretical observations.
We examined two commonly used dichotic listening tests for measuring the degree of hemispheric specialization for language in individuals who had undergone cerebral hemispherectomy: the consonant-vowel (CV) nonsense syllables and the fused words (FW) tests, using the common laterality indices f and lambda. Hemispherectomy on either side resulted in a massive contralateral ear advantage, demonst...
متن کاملMolecular Pathophysiology of Cerebral Hemorrhage
Intracerebral hemorrhage (ICH) is an often fatal type of stroke that kills 30 000 people annually in the United States. If the patient survives the ictus, then the resulting hematoma within brain parenchyma triggers a series of adverse events causing secondary insults and severe neurological deficits. This article discusses selected aspects of secondary brain injury after ICH and outlines key m...
