Posterior callosal section in a non-epileptic patient.
The major studies of the effects of callosal section in humans have been conducted in severe epileptic patients in whom commissurotomy has been performed for management of intractable seizures. In spite of the evidence which has been amassed it is possible to criticise the results, on the grounds that all patients had seizures for many years prior to surgery and hence it is conceivable that som...
متن کاملPrehension movements in a patient (AC) with posterior parietal cortex damage and posterior callosal section.
Prehension movements of the right hand were recorded in a right-handed man (AC), with an injury to the left posterior parietal cortex (PPC) and with a section of the left half of the splenium. The kinematic analysis of AC's grasping movements in direct and perturbed conditions was compared to that of five control subjects. A novel effect in prehension was revealed--a hemispace effect--in health...
متن کاملSplitting of the P3 component during dual-task processing in a patient with posterior callosal section.
When two concurrent sensorimotor tasks have to be performed at a short time interval, the second response is generally delayed at a central decision stage. However, in patients who have undergone full or partial transection of forebrain fibers connecting the two hemispheres (split-brain), independent structures subserving all processing stages should reside in each disconnected hemisphere, thus...
متن کاملPerceptual and attentional processes following callosal section in humans.
Studies are reviewed that examine how perceptual and attentional systems operate in the cortically disconnected human. The data indicate that even though both simple and complex perceptual information associated with the cognitive activities of each disconnected half brain show virtually no interactions, the attentional system remains largely integrated in the split-brain patient. It also appea...
متن کاملPatient and caregiver quality of life in psychogenic non-epileptic seizures compared to epileptic seizures
PURPOSE Little is known about the effect of psychogenic non epileptic seizures (PNES) to caregiver quality of life (QOL), particularly as it compares to epileptic seizures (ES). We sought to characterize this effect and identify its determinants. METHODS The study population comprised of 126 ES and 33 PNES patients who underwent video EEG monitoring along with 48 and 18 caregivers respectivel...
