Resting-state fMRI after experimental hemispherectomy in rats: changes in functional connectivity and network synchronization
Introduction Hemispherectomy is a last resort treatment for children with catastrophic hemispheric epilepsy. It abolishes seizures and improves quality of life. The remarkable motor recovery after hemispherectomy, observed in both clinical and experimental settings, reflects the plastic capacities of the brain, especially at young age. Direct cortical stimulation of the healthy hemisphere in ad...
متن کاملLanguage after hemispherectomy.
We studied the spoken language of 49 children who had undergone hemispherectomy as part of the UCLA Pediatric Epilepsy Surgery Research Program and analyzed, among a number of clinical factors, the relation between acquired vs developmental pathology and spoken language outcomes. In this paper we will briefly review the results of our study and attempt to explain (1) why "the early" is not alwa...
متن کاملLanguage after dominant hemispherectomy.
Linguistic and related cognitive abilities were investigated two years after dominant left hemispherectomy for cerebral malignancy in a 12 year old female. Auditory comprehension of speech was superior to other modes of language abilities with expressive speech being the least developed. Findings suggested an isolation or non-communication between the systems for speaking and for writing and vi...
متن کاملPattern 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, ...
