BACKGROUND AND PURPOSE Further recovery from stroke can occur late, long after the end of the apparent evolution of pathological changes. This observation and evidence obtained from functional imaging for altered patterns of activation after brain injury suggest that cortical reorganization may contribute to recovery. Here, we have tested for potentially(More)
BACKGROUND AND PURPOSE Blood oxygenation level-dependent (BOLD) functional MRI (fMRI) is a promising method for defining brain recovery after stroke quantitatively. Applications thus far have assumed that the BOLD hemodynamic response in patients after stroke is identical to that in healthy controls. However, because of local vascular compromise or more(More)
BACKGROUND AND PURPOSE Infarct size on T2-weighted MRI correlates only modestly with outcome, particularly for small strokes. This may be largely because of differences in the locations of infarcts and consequently in the functional pathways that are damaged. To test this hypothesis quantitatively, we developed a "mask" of the corticospinal pathway to(More)
In this paper, we describe the compilation and structure of two linguistic resources, a corpus and a dictionary of terms of the field of economy, developed for Galician. Together with this, we describe the use of these resources for the automatical extraction of multi-word terms by means of a combination of linguistic and statistical techniques. While doing(More)
Sentence word segmentation and Part-Of-Speech (POS) tagging are common pre-processing tasks for many Natural Language Processing (NLP) applications. This paper presents a practical application for POS tagging and segmentation disambiguation using an extension of the one-pass Viterbi algorithm called Viterbi-N. We introduce the internals of the developed(More)
In this paper, we introduce a tagger environment for Galician, the native language of Galicia. Galician belongs to the group of Romance languages which developed from the Latin imposed on the northwest of the Iberian Peninsula by the Romans, with additions from the languages of peoples living here before the colonization, as well as contributions from other(More)
INTRODUCTION AND OBJECTIVES We present a review on the technical, methodological and clinical advances in the functional study of the brain by means of magneto-encephalography. We look back the milestones of its historical development, through the work of the major research groups on this field and through our group's works and database (including doctoral(More)
