The ability to learn to criterion a visually-guided stylus maze was found impaired in patients with right posterior cerebral damage, not only in comparison with controls but also with other hemisphere-damaged groups. The contribution of the corresponding left sided area to this task is dubious, and certainly not substantial. This finding points to the independent organisation of long-term spati...

Remotely sensed data are essentially used for land cover and vegetation classification. However, classes of interest are often imperfectly separable in the feature space provided by the spectral data. One of the most common attempts to improve image classification is the integration of ancillary data into classification. In this study, an approach for integrating topographic data into land cove...

Research during the past two decades has demonstrated an important role of the vestibular system in topographical orientation and memory and the network of neural structures associated with them. Almost all of the supporting data have come from animal or human clinical studies, however. The purpose of the present study was to investigate the link between vestibular function and topographical me...

The paper deals some problems with the scale and the possible concepts development of national topographical data infrastructure. There are two concepts in the procedure of structuring and updating of topographical data in digital (vector) form: model stars (discrete) and model steps (continuous). The discrete model consists of some basic data of framework. So, each of those data is updated sep...

OBJECTIVE To estimate the prevalence of topographical memory impairment following posterior cerebral artery infarctions (PCAI) and define its anatomical correlations. METHODS We recruited 15 patients (mean duration of 4 months postinfarct). We administered 2 sets of experimental tests to assess topographical memory: one set included 5 computerized tasks (CompT) and the other set consisted of ...
