A disconnection account of Gerstmann syndrome: functional neuroanatomy evidence.
OBJECTIVE To examine the functional neuroanatomy that could account for pure Gerstmann syndrome, which is the selective association of acalculia, finger agnosia, left-right disorientation, and agraphia. METHODS We used structural and functional neuroimaging at high spatial resolution in healthy subjects to seek a shared cortical substrate of the Grundstörung posited by Gerstmann, ie, a common...
متن کاملToe agnosia in Gerstmann syndrome.
The following case report presents a patient exhibiting Gerstmann syndrome accompanied by toe agnosia. A 72 year old right handed woman had a focal lesion in the angular gyrus of the left hemisphere which was caused by a glioblastoma multiforme. The first symptom she had complained of was severe headache. Standardised neuropsychological tests of intelligence, memory, attention, fluency, apraxia...
متن کاملThe Gerstmann syndrome in Alzheimer's disease.
BACKGROUND It remains unclear from lesion studies whether the four signs of the Gerstmann syndrome (finger agnosia, acalculia, agraphia, and right-left confusion) cluster because the neuronal nets that mediate these activities have anatomical proximity, or because these four functions share a common network. If there is a common network, with degeneration, as may occur in Alzheimer's disease, e...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولFunctional anatomy of motor urgency
This PET H(2)(15)O study uses a reaching task to determine the neural basis of the unconscious motor speed up observed in the context of urgency in healthy subjects. Three conditions were considered: self-initiated (produce the fastest possible movement toward a large plate, when ready), externally-cued (same as self-initiated but in response to an acoustic cue) and temporally-pressing (same as...
