Thigmotactic responses in an open-field.
The goal of the present study was to investigate the role of thigmotaxis (the tendency to remain close to vertical surfaces) in rat exploratory behavior in an open-field. Thigmotaxis was investigated in a parametric way, using 24 experimentally adult naive male Wistar rats (210-230 g). Exploratory behavior was studied in an open-field (N = 12) in 5-min sessions and behavior was analyzed in term...
متن کاملAn Assessment of Changes in Open-Field and Elevated Plus-Maze Behavior Following Heat Stress in Rats
This paper presents the effect of high environmental heat on behavior of the male Charles Foster rats. Eighty rats were divided into three groups, subjected to (i) acute heat stress (ii) chronic heat stress and (iii) handling control group. Animals were exposed to the hot environment in a biological oxygen demand incubator at 38 ± 1ºC (relative humidity 45-50%) for four hours of continuous sing...
متن کاملCopulas: an open field for risk management
One of the main issues of risk management is the aggregation of individual risks. A powerful concept to aggregate the risks — the copula function — has been introduced in finance by Embrechts, McNeil, and Straumann [1999,2000]. In their papers, the authors clarify the essential concepts of dependence and correlation and certainly will greatly influence the risk management industry. The goal of ...
متن کامل'Looping'-an exploration mechanism in a dark open field.
The behavior of Tristram's jird (a species of gerbil) in an illuminated open field resembled that of other rodents, comprising round trips to a home base and alternating between periods of progression (locomoting) and of stopping. In this study, we compared the characteristics of exploration in a dark arena with exploration by the same individuals in a lit arena. In the dark arena, stopping epi...
