In open field arenas, Drosophila adults exhibit a preference for arena boundaries over internal walls and open regions. Herein, we investigate the nature of this preference using phenomenological modeling of locomotion to determine whether local arena features and constraints on movement alone are sufficient to drive positional preferences within open field arenas of different shapes and with d...

Arena structure caused by restricted spatial distribution of predators relative to prey 45 Restricted predator distribution in response to predation risk caused by its predators 45 Restricted predator distribution caused by limited predator mobility or habitat requirements 45 Restricted prey distribution and/or activity 47 Time allocation to safe/resting sites 47 Abstract There is a critical ne...

China is the most promising game market in world. However, with development of industry, Chinese facing a severe problem - addiction to games among youth group. The issue has become that cannot be ignored society. How operators should actively respond national policy and simultaneously cope social resistance first needs solved. Based on above background, this study selects typical case China’s ...

Geometric alterations to the boundaries of a virtual environment were used to investigate the representations underlying human spatial memory. Subjects encountered a cue object in a simple rectangular enclosure, with distant landmarks for orientation. After a brief delay, during which they were removed from the arena, subjects were returned to it at a new location and orientation and asked to m...

Drosophila adults, when placed into a novel open-field arena, initially exhibit an elevated level of activity followed by a reduced stable level of spontaneous activity and spend a majority of time near the arena edge, executing motions along the walls. In order to determine the environmental features that are responsible for the initial high activity and wall-following behavior exhibited durin...
