In ‘left’ neglect—a frequent consequence of damage to posterior areas of the right cerebral hemisphere—the relational term ‘left’ immediately raises the question ‘left of what?’. It is shown that on a simple copying task the answer can be ‘left of the principal axis of the object or objects depicted’. Under conditions in which the stimulus material was intrinsically controlled for lateral extent and position, ‘object-centred’ neglect seemed to reflect some basic principles of perceptual parsing.

The smelling behavior of 52 right-handed subjects was videotaped during tasks involving identification and recognition of different odors. Analysis showed that men more often used the right nostril than the left whatever the odor. There was no significant difference for the women. These results support a more marked cerebral asymmetry in men than in women and a main involvement of the right cerebral hemisphere in the olfactory processes at least by right-handed men.

ABSTRACT The role of the right cerebral hemisphere (RH) associated with semantic priming effects (SPEs) must be better understood, since the consequences of RH damage on SPE are not yet well established. Objective: The aim of this article was to investigate studies analyzing SPEs in patients affected by stroke in the RH through a systematic review, verifying whether there are deficits in SPEs, and whether performance varies depending on the type of semantic processing evaluated or stimulus in the task. Methods: A search was conducted on the LILACS, PUBMED and PSYCINFO databases. Results: Out of the initial 27 studies identified, 11 remained in the review. Difficulties in SPEs were shown in five studies. Performance does not seem to vary depending on the type of processing, but on the type of stimulus used. Conclusion: This ability should be evaluated in individuals that have suffered a stroke in the RH in order to provide treatments that will contribute to their recovery.

We report a right-handed man who developed selective Kana (phonogram) agraphia following an infarct in the non-dominant right cerebral hemisphere. His ability for comprehension, reading and writing of Kanji (ideogram) was unaffected. Kana errors consisted of substitution with another letter and the number of target words was well preserved. The lesion responsible for his Kana agraphia included the right Wernicke's area (the posterior one-third or one-half of the superior temporal gyrus) on MRI, but he did not have aphasia. Based on these findings, we conclude that the language function in some dextral people may be partially lateralized to the right cerebral hemisphere.

The article theoretically and practically substantiates the necessity of teaching Mapping for Bachelors of Tourism. The cartographic competence of future professionals is closely connected with their professional skills. The specific feature of the cartographic method is that it allows one to visualize the geographic space or any simulated space for studying. Consequently it develops the student’s spatial thinking, and makes both cerebral hemispheres be active. It is known that the right cerebral hemisphere is responsible for the creative feature of the human nature, and the left cerebral hemisphere is responsible for the logic. The essence of the cartographic method is that in the process of researching the reality an intermediate element appears. And the intermediate element is a map the role of which is of two kinds: it is a research tool and the subject of research presented as a model, a prototype of the reality at the same time. The symbolic figurative language of a map develops the abstract thinking about the real prototype. It should be emphasized that maps help specialists to establish new patterns in location and interconnection of phenomena. Understanding of the graphic image of the structure of the geographical space, highlighting the peculiarities of the tourist and recreational component, administrating the tourist and recreational space, designing a regional project for the development of tourism, creating package tours – all these professional skills are immediately related to students’ intellectual-graphic activities, to their abilities to visualize the geospace, to be good at Mapping. In the final part of the article the cartographic competence is defined as an element of the culture of a competent specialist in tourism’s personality.
