Reports of sex differences in wayfinding have typically used paradigms sensitive to the female advantage (navigation by landmarks) or sensitive to the male advantage (navigation by cardinal directions, Euclidian coordinates, environmental geometry, and absolute distances). The current virtual navigation paradigm allowed both men and women an equal(More)
The present research examined the relationship between endogenous glucocorticoids, navigational strategies in a virtual navigation task, and performance on standard neuropsychological assessments of memory. Healthy young adult participants (N=66, mean age: 21.7) were tested on the 4 on 8 virtual maze (4/8 VM) and standard neuropsychological tests such as(More)
The hippocampus and the caudate nucleus are critical to spatial- and stimulus-response-based navigation strategies, respectively. The hippocampus and caudate nucleus are also known to be anatomically connected to various areas of the prefrontal cortex. However, little is known about the involvement of the prefrontal cortex in these processes. In the current(More)
Large displays and stereopsis have been shown to improve performance in several virtual navigation tasks. In the present research, we sought to determine whether wayfinding could benefit from these factors. Participants were tested in a virtual town. There were three viewing conditions: a desktop, a large screen, and a large screen on which the virtual(More)
The aim of this study was to investigate the hypothesis that semantic information facilitates auditory and visual spatial learning and memory. An auditory spatial task was administered, whereby healthy participants were placed in the center of a semi-circle that contained an array of speakers where the locations of nameable and non-nameable sounds were(More)
BACKGROUND In order to simplify the national data collection related to diarrhea, a sentinel surveillance system was implemented in the Ksar-Hellal district (Tunisia). POPULATION AND METHODS This system was based on 461 cases of diarrhea collected from health centers and hospitals between June 1994 and December 1995. RESULTS The collected information(More)
1 The BDNF val66met polymorphism predicts human spatial memory behaviour, fMRI activity and brain morphology Acknowledgements Scientific exploration is never an individual pursuit. I am extremely grateful for the inspiration and collaboration of my colleagues past and present in the Memory &motion Laboratory. In particular, I would like to thank(More)
