In the present study, we introduce an experimental procedure to study, in rats, a wide range of natural defensive reactions. Animals were tested in an experimental apparatus that consisted of a home cage (25 x 25 x 25 cm) connected to another chamber (25 x 25 x 25 cm-the food compartment) by a hallway (12.5 cm wide and 100 cm long, with 25-cm high walls). During 10 days before the testing procedures, each animal was isolated in the home cage, and, at the beginning of the dark phase, allowed to… Expand

The exploratory behavior of rats in an open environment optimizes security
TLDR
The pattern of behavior, in which the rats failed to explore from a secure starting position and were increasingly likely to run away as security decreased, suggests that a primary function of locomotor behavior in a novel environment is to optimize security. Expand
Conditioned behavioral responses to a context paired with the predator odor trimethylthiazoline.
TLDR
Results indicate that expression of conditioned fear behavior in response to a TMT-paired context is dependent on the experimental setup used, as well as the strategy of the individual rat. Expand
Risk assessment and avoidance in juvenile golden hamsters exposed to repeated stress
TLDR
The extent to which social subjugation stimulates fear- or anxiety-like behavior in juvenile hamsters in both social and non-social contexts was determined and subjugated juveniles learned to avoid adult males and were otherwise behaviorally similar to non-subjugated controls. Expand
Central infusion of ovine CRF (oCRF) potentiates defensive behaviors in CD-1 mice in the Mouse Defense Test Battery (MDTB)
TLDR
Findings indicate that non-selective activation of corticotropin-releasing factor (CRF) receptors via ventricular infusion of oCRF potentiates defensive behaviors relevant to the demand of specific challenges, generally enhancing the predominant defensive behavior in each specific situation. Expand
Testing conditions in shock-based contextual fear conditioning influence both the behavioral responses and the activation of circuits potentially involved in contextual avoidance
TLDR
The present findings show that testing conditions significantly influence both behavioral responses and the activation of circuits involved in contextual avoidance. Expand
The differential mice response to cat and snake odor
TLDR
It is concluded that not all the predator cues are sufficient to activate the predator-responsive hypothalamic circuit of mice and that their response depends on the danger that these predators represent in the natural history of the prey. Expand
Conditioning properties of social subordination in rats: Behavioral and biochemical correlates of anxiety
TLDR
Overall, these data demonstrate the induction of an anxiety-like state in rats through a context conditioning process based upon social factors, and may provide a useful experimental model to further investigate the neurobiological mechanisms underlying anxiety-related disorders. Expand
Scopolamine Induces Deficits in Spontaneous Object-Location Recognition and Fear-Learning in Marmoset Monkeys
TLDR
SCP impaired the marmosets’ short-term ability to detect changes associated with the spatial location of ethologically irrelevant stimuli and relevant stimuli and may help reduce the translational gap between pre-clinical studies and memory-associated human pathologies. Expand
Short-Term Enrichment Makes Male Rats More Attractive, More Defensive and Alters Hypothalamic Neurons
TLDR
Behavioral and hormonal observations provide evidence that a short period of environmental manipulation can alter innate behaviors, providing a good example of gene-environment interaction. Expand
The defensive behavioral patterns of captive white-lipped and collared peccary (Mammalia, Tayassuidae): an approach for conservation of the species
TLDR
The hypothesis that the collared peccaries’ cautiousness may help to prevent a decrease in its population, while the white-lipped peccary’s exploratory and confrontational behavioral patterns in overhunted areas, together with other simultaneous factors as forest fragmentation, might contribute to placing this species in the vulnerable category is confirmed.

Low-Dose Midazolam Attenuates Predatory Odor Avoidance in Rats
TLDR
Low-dose midazolam is an effective anxiolytic agent in rats during exposure to predatory odor using a novel apparatus that allowed rats to hide from the odor in a small wooden "hide box" placed within a larger arena. Expand
Behavioral and Endocrine Change Following Chronic Predatory Stress
TLDR
Findings of organ weight changes, enhanced basal CORT, and reduced CORT response to stress in a subgroup of animals are similar to many of the phenomena obtained with other intense, chronic stressors such as subordination, and suggest that repeated predator exposure produces a pattern of intense behavioral and endocrine response that is very slow to habituate. Expand
Cue and context conditioning of defensive behaviors to cat odor stimuli
TLDR
The behaviors seen to the conditioned stimulus appeared to reflect combinations of different defense strategies, appropriate to the type of conditioned stimulus and responsive to its extinction, which suggests that the latter may not elicit a complete range of conditioned defenses. Expand

‘When a rat smells a cat’: the distribution of Fos immunoreactivity in rat brain following exposure to a predatory odor
TLDR
Robust Fos expression in the ventromedial hypothalamus, premamillary nucleus and periaqueductal gray confirms previous suggestions of a role for these areas in predator-induced defensive behavior and draws attention to this subregion as a possible interface between olfactory input and emotional output.

TLDR
It is suggested that the Mouse Defense Test Battery is a sensitive and appropriate tool for preclinical evaluation of drugs potentially effective against defense-related disorders such as anxiety and panic. Expand
PREDATOR VIGILANCE AND GROUP SIZE IN MAMMALS AND BIRDS: A CRITICAL REVIEW OF THE EMPIRICAL EVIDENCE
  • M. Elgar
  • Psychology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 1989
TLDR
Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research. Expand
Dorsal premammillary nucleus differentially modulates defensive behaviors induced by different threat stimuli in rats
TLDR
Findings of reduced defensiveness of PMd-lesioned rats to a cat are confirmed, extending the pattern of reduceddefensiveness to cat odor stimuli as well, but also suggest that such lesions have few effects on nonolfactory threat stimuli. Expand
