Cerebrovascular Brainstem Diseases with Isolated Cranial Nerve Palsies

2002

There is a significant number of individual patients with cranial nerve palsies as the sole manifestation of MRI- and, less frequently, CT-documented small brainstem infarctions or hemorrhages. The 3rd and 6th nerves are most commonly involved and, less frequently, the 4th, 5th, 7th, and 8th nerves. An intra-axial basis for such lesions may be underestimated if the diagnosis is based solely on MRI. The electrophysiologic abnormalities indicating brainstem lesions may be independent of MRI-documented morphological lesions. This paper reviews the literature on cerebrovascular brainstem diseases manifesting as isolated cranial nerve palsies. It supports the concept that small pontine and mesen…

Third nerve palsy as the sole manifestation of midbrain ischemia

1995

Thirty-seven patients with risk factors for the development of cerebrovascular diseases had sudden onset isolated third nerve palsy and abnormal masseter reflex and/or electro-oculographic findings indicating a causative midbrain lesion. Improvement or recovery of the third nerve palsies was accompanied by improvement or recovery of the abnormal electrophysiologic findings pointing to their functional significance. Magnetic resonance imaging (MRI) in 29 of these patients demonstrated corresponding ischemic midbrain lesions in eight, ipsilateral in five patients, bilateral in three. In another three patients with MRI proven midbrain lesions (ipsilateral in two, bilateral in one) electrophysi…

Entornos virtuales de aprendizaje: modelo ampliado de aceptación de la tecnología

2019

Dentro de la actual renovación de las metodologías docentes, las universidades están impulsando el uso de entornos virtuales de aprendizaje como una herramienta básica en la enseñanza presencial, ya que permite flexibilizar e individualizar la educación. El objetivo del presente trabajo es aportar evidencia empírica sobre la percepción que tienen los alumnos respecto a la mejora en su aprendizaje, al adoptar y utilizar entornos virtuales en la enseñanza presencial, a partir del Modelo de Aceptación de la Tecnología ampliado. La población objeto del estudio son 251 casos de estudiantes de primer grado de la Facultad de Economía de la Universitat de Valencia. Se ha evidenciado empíricamente, …

An Emulator Toolbox to Approximate Radiative Transfer Models with Statistical Learning

2015

Physically-based radiative transfer models (RTMs) help in understanding the processes occurring on the Earth’s surface and their interactions with vegetation and atmosphere. When it comes to studying vegetation properties, RTMs allows us to study light interception by plant canopies and are used in the retrieval of biophysical variables through model inversion. However, advanced RTMs can take a long computational time, which makes them unfeasible in many real applications. To overcome this problem, it has been proposed to substitute RTMs through so-called emulators. Emulators are statistical models that approximate the functioning of RTMs. Emulators are advantageous in real practice because…

A visualization technique for accessing solution pool in interactive methods of multiobjective optimization

2015

<pre>Interactive methods of <span>multiobjective</span> optimization repetitively derive <span>Pareto</span> optimal solutions based on decision maker's preference information and present the obtained solutions for his/her consideration. Some interactive methods save the obtained solutions into a solution pool and, at each iteration, allow the decision maker considering any of solutions obtained earlier. This feature contributes to the flexibility of exploring the <span>Pareto</span> optimal set and learning about the optimization problem. However, in the case of many objective functions, the accumulation of derived solutions makes accessing the sol…

Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia

2021

Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…
