SummaryThe mantis shrimpSquilla mantis responds to an electrical shock with a quick and violent flexure of its body (Fig. 1 and 2). The reaction time of this defensive response was measured for each experimental shrimp and the minimal current that elicited a reaction time equal to or lesser than 0.22 s was considered as its intensity threshold (Fig. 3). Different doses of morphine-HCl were injected and results showed that this drug produces a dose-related analgesia by increasing the intensity… 

Habituation in the crabChasmagnathus granulatus: effect of morphine and naloxone

TLDR
Results concerning stimulus generalization and dishabituation strongly suggest that neither motor fatigue nor sensory adaptation can account for the response waning, and the potential value of the response habituation as a model for studying both habituation dynamics and the mechanisms that subserve it is discussed.

Behavioral and Pharmacological Analysis of the Stinging Response in Africanized and Italian Bees

TLDR
Results obtained after morphine and naloxone + morphine treatment on bees suggest the existence of an endorphinic system for pain modulation, but its implication for the observed sensitivity changes is not yet known.

Assessing the Potential for Pain in Crustaceans and Other Invertebrates

TLDR
Available data go beyond the idea of just nociception, but the impossibility of total proof of pain means they are not definitive, Nevertheless, more humane care for invertebrates is suggested.

Pain and suffering in invertebrates?

TLDR
Criteria that might distinguish nociception from pain are reviewed and an ability to use complex information suggests sufficient cognitive ability for the animal to have a fitness benefit from a pain experience is suggested.

Potential Pain in Fish and Decapods: Similar Experimental Approaches and Similar Results

    Frontiers in Veterinary Science
  • 2021
TLDR
The results reported for the two taxonomic groups are remarkably similar and indicate that responses of both go beyond those expected of mere nociceptive reflex, which means that both fish and decapods should be awarded consideration for their welfare.

Comparative aspects of opioid-dopamine interaction

TLDR
The results obtained in the molluskMytilus strengthen the concept that the activity of dopaminergic neurons may be modulated by afferent opioid signals and that, even in “more primitive” animals, interneuronal transfer of information is more complex than formerly visualized.

Review of some scientific issues related to crustacean welfare

  • B. Diggles
  • Biology

  • 2018
TLDR
The proposed criteria for pain being applied to crustaceans since 2014 has set the “evidential bar” for pain so low it is impossible to have confidence that the behaviours observed in many experiments are even due to nociception, extinguishing scientific confidence that these behaviours are in any way analogous to how the word pain is defined, used, and understood by humans.

Quantitative studies on the antagonism by naloxone of some narcotic and narcotic‐antagonist analgesics

TLDR
The results suggest that the Narcotic and the narcotic‐antagonist analgesics may inhibit stretching in this assay by interacting either with two different receptors or with the same receptor in a different manner.

EFFECT OF MORPHINE ON ADRENERGIC TRANSMISSION IN THE MOUSE VAS DEFERENS. ASSESSMENT OF AGONIST AND ANTAGONIST POTENCIES OF NARCOTIC ANALGESICS

TLDR
The fact that the agonist effects of drugs with dual agonist and antagonist action show little or no dependence on concentration, makes the mouse vas deferens particularly suitable for the assay of antagonist activity.

Naloxone blockade of morphine analgesia: a dose-effect study of duration and magnitude.

TLDR
The results indicate that 1.0 mg/kg of naloxone is the minimum dose necessary to provide full blockade of the measured morphine effect for up to 5 hours after the morphine administration.

OPIATE BINDING AND EFFECT IN ILEUM PREPARATIONS FROM NORMAL AND MORPHINE PRETREATED GUINEA‐PIGS

TLDR
Tolerance to opiate effect was not accompanied by a change in the affinity or number of stereo‐specific binding sites for [3H]‐etorphine, and the assumption that in tolerant preparations, a certain fractional opiate receptor occupation threshold must be exceeded before opiate effects become apparent is explained.

Regional sensitivity of the rat brain to the inhibitory effects of morphine on wet shake behavior.

TLDR
It is concluded that the central inhibitory effects of morphine on shaking are subserved by discrete neuroanatomical substrates located in medial subcortical structures.
