How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Objective: To evaluate the precision, effectiveness and safety in the identification and lesion of subthalamic nucleus using a new surgical strategy, guided by images and multi-unit deep brain electrical recording. Special attention was given to ventricular dilation and cerebral atrophy in relation to electrode trajectory and the accuracy of the su...
Introducción La efectividad y seguridad de la cirugía ablativa en los trastornos del movimiento (Enfermedad de Parkinson (EP), distonías y temblor esencial) dependen, entre otros elementos, de la localización de las lesiones en las regiones nucleares de interés y del volumen de estas lesiones. Este trabajo tiene como objetivo mostrar los métodos...
Background: Persistent vegetative states (PVS) and locked-in syndrome (LIS) are well differentiated disorders of consciousness that can be reached after a localized brain injury in the brainstem. The relations of the lesion topography with the impairment in the whole-brain architecture and functional disconnections are poorly understood. Methods: T...
Functional neuroimaging has provided new insights for the asses sment of cerebral function in disorders of consciousness (DOC). Recent advances have made possible to reliably identify functional and anatomical brain networks, by resting state functional magnetic resonance imaging and diffusion tensor connectivity analyses. However, this approach i...
Diffusion tensor imaging is an ideal technique with which to study it in order to detect the degree of integrity of white matter. WE attempted to establish a method to explore the microstructural integrity of white matter in children autism using diffusion tensor imaging and fiber tractography algorithms. In this study we propose a method for a DTI...
