Elicitation of aggression by food deprivation in olfactory bulbectomized male mice

摘要: Two experiments were conducted in order to examine the necessary conditions for elicitation of competitive aggression olfactory bulbectomized male mice. Experiment 1 compared fighting produced among pairs males under either food deprivation or ad-lib feeding, with and without presence a food-pellet/competition-eliciting stimulus. Animals fought when food-deprived but not sated. The pellet was promotion aggression. 2 sought remove condition isolation pretest housing. However, males, housed pairs, placed upon food-deprivation schedule, one member inevitably cannibalized. Identically treated controls died before exhibiting any cases cannibalism. These findings indicate that is sufficient reinstate intraspecific mice, as well combine effects bulbectomy promote normally inhibited
