Background: The language lateralization index (LI) is a valuable tool in functional magnetic resonance imaging (fMRI) research, especially in people with post-stroke aphasia. However, there is inconsistent consideration for the overlap of lesions with regions of interest (ROIs). The purpose of this study was to determine whether standard LI (SLI) and lesion-adjusted LI (LALI) formulae generate ...
Reorganization of eloquent cortex enables rescue of language functions in patients who sustain brain injury. Individuals with left-sided, early-onset focal epilepsy often show atypical (i.e. bilateral or right-sided) language dominance. Surprisingly, many patients fail to show such interhemispheric shift of language despite having major epileptogenic lesions in close proximity to eloquent corte...
Title of Dissertation: MATHEMATICAL MODELING OF LATERALIZATION AND ASYMMETRIES IN CORTICAL MAPS Svetlana Levitan, Doctor of Philosophy, 1999 Dissertation directed by: Professor James A. Reggia Applied Mathematics Program Recent experimental work in neurobiology has de ned asymmetries and lateralization in the topographic maps found in mirror-image regions of the sensorimotor cerebral cortex. Ho...
The asymmetric development of the cerebellum has been reported in several mammalian species. current study quantitatively characterized cerebellar asymmetry and sexual dimorphism cynomolgus macaques using magnetic resonance (MR) imaging-based volumetry. Three-dimensional T1W MR images at 7-tesla were acquired ex vivo from fixed adult male (n = 5) female monkey brains. Five transverse domains co...
