TLDR
A number of general concepts are discussed, for example the relation of convulsions to flight behaviour, the reduction of incoming aggressive stimuli in submissive postures, "Cut-Off", and the inhibition of biting in the more social species.Abstract:
This paper describes elements in the social behaviour of the laboratory rat, mouse, hamster and Guinea-pig. These elements are divided into postures, which are static, and acts, which involve movement. A total of 45 of these elements are mentioned, most of which are common, with only slight modification, to all four species. Apart from these the guinea pig differs in not having a true Upright Posture and also in showing a male sexul display "Rumba". The postures are classified under broad motivational headings. A number of general concepts are discussed, for example the relation of convulsions to flight behaviour, the reduction of incoming aggressive stimuli in submissive postures, "Cut-Off", and the inhibition of biting in the more social species.read more

Pharmacological evidence for a role of D2 dopamine receptors in the defensive behavior of the mouse
TL;DR: Results indicate that D2 receptors play a major role in the expression of defensive behavior in the mouse and the hypothesis that alteration in D2 receptor functioning may produce hyperdefensiveness possibly due to altered perceptive processes is discussed.

Differential roles of the dorsal and ventral hippocampus in predator odor contextual fear conditioning.

TL;DR: It is found that contextual conditioning induced by exposure to coyote urine produces long‐term freezing, a stereotypic response to fear observed in mice, and region‐specific lesions of the dorsal and ventral hippocampus indicate that both areas are independently required for the long-term expression of learned fear.

An ethological model for the study of activation and interaction of pain, memory and defensive systems in the attacked mouse. Role of endogenous opioids.
TL;DR: The present work reviews neurochemical, physiological and behavioral data recorded from the attacked mouse and integrates them into a model of coping mechanisms during social conflict, with special emphasis on the role of endogenous opioid peptides.

The effect of familiar visual and olfactory cues on the aggressive behaviour of mice
R.B. Jones,N.W. Nowell +1 more
TL;DR: It is shown that familiar olfactory cues have a greater enhancing effect on aggression than do familiar visual cues and is explained in terms of the conflict between attack and competing behaviours.

Escalated aggression after alcohol drinking in male mice: dorsal raphé and prefrontal cortex serotonin and 5-HT(1B) receptors.
TL;DR: It is suggested that 5-HT1B receptors in the mPFC may serve to selectively disinhibit aggressive behavior in mice with a history of Alc self-administration.

An analysis of the social behaviour of the male laboratory rat
TL;DR: It is suggested that there are two main Flight pathways, one leading to a Submissive Posture and the other to Crouch or Retreat, the occurrence of these is related to two types of behaviour seen in the wild, intra-colonial and territorial.

An analysis of social behaviour in wild rats
TL;DR: A small number of experiments with R. rattus showed that this species possesses all the components of amicable and aggressive behaviour observed in R. norvegicus, but that it is less fierce and more agile.

The Aggressive Behaviour of the Vole
TL;DR: In this article, a laboratory study of the aggressive behaviour of the vole (Microtus agrestis) has been made as part of an investigation of the consequences of CHITTY's hypothesis concerning the cause of vole population cycles.

Rank order in caged rats
E.C. Grant,M.R.A. Chance +1 more
TL;DR: Rank order was found to develop in cages containing 2, 3, 4 and 5 male rats but not in cagescontaining 6 male rats when assessed during the first three weeks after weaning, providing confirmatory evidence that the groups possess a stable structure.
