Observación del comportamiento y bienestar de ratas wistar en su alojamiento en el ciclo de luz normal

Abstract

Most living things have a circadian rhythm that extends for about 24 hours (Meulen, 2014). In this circadian rhythm we distinguish an active phase and a rest phase. Rodents are nocturnal animals, meaning they are active at night when there is little or no light present (Meulen, 2014). The manipulation of this cycle has effects on the physiology (Clénet, Bouyon, Hascoët, & Bourin, 2006) (Davidson, Sellix, Yamazaki, Menaker, & Block, 2006) Bourin, 2006) (Meulen, 2014). In the context of the learning practices of the Animal Behavior laboratory of the Konrad Lorenz University Foundation, research projects related to the procedures performed during the practice are formulated. The analyzes presented in this work are derived from the project entitled "Effect of external and organic keys on the renewal of the conditioned response of leverage", proposed by the teacher Victor Oswaldo Gamboa. This project aimed to observe the effect of circadian cycles on behavior in a paradigm of behavior renewal. Within this research proposal, with the theoretical-practical work of the internship, it was proposed to evaluate the behavior and well-being of Wistar rats in their housing boxes while they were in the experimental phases of the normal light cycle.
