Opioid action on response level to a danger stimulus in the crab (Chasmagnathus granulatus).

TLDR
Results suggest that morphine acts through an opiate receptor to inhibit the crab's response level to a danger stimulus and the most viable one suggests a central site of action.

Nonhabituation processes affect stimulus specificity of response habituation in the crab Chasmagnathus granulatus.

TLDR
The results support the hypothesis that during the crab's training two types of processes takes place: a stimulus-specific, long-lasting habituation process that promotes between-sessions response habituation and a nonhabituationprocess that promotes nonstimulus- specific, less persistent changes of behavior that involve either response habituated or response sensitization.

Exposure to novelty induces naltrexone-reversible analgesia in rats.

TLDR
The data suggest that novelty per se is a sufficient stimulus to activate an opioid-mediated analgesic stimulus in rats made familiar with the test situation.

TLDR
This experimental design has revealed that controllability exerts important modulatory effects on both behavioral and physiological changes produced by exposure to a stressor.

Exposure to a cat produces opioid analgesia in rats.

TLDR
In both experiments, rats tested in the presence of the cat showed a significant reduction in sensitivity/reactivity to a skin-irritating formalin injection, and naltrexone reversed this analgesia.

Odors released by stressed rats produce opioid analgesia in unstressed rats.

TLDR
The data suggest that naturalistic stimuli innately associated with aversive environmental events can activate endogenous pain control mechanisms.
