Male crabs Chasmagnathus granulatus were trained by means of a method similar to the standard inhibitory avoidance technique widely used in vertebrates. Each crab was placed in the dark compartment (DC) of a double-chamber device, allowed to move towards the light compartment (LC) and latency to enter measured. Experimental crabs received a shock in LC, but controls were not punished. After 1 min, both experimental and control crabs were free to return to DC. On completion of 1, 2, 3 or 24 hr… Expand
Multitrial inhibitory avoidance learning in the crab Chasmagnathus.
TLDR
Experimental devices previously used in avoidance learning studies with crabs were improved here by automating both the computation of latency values and the event recording, suggesting that crabs learn to associate the LC with an aversive situation. Expand
Habituation and associative learning during exploratory behavior of the crab Chasmagnathus
SummaryChasmagnathus crabs placed in a choice-chamber device (a dark compartment, DC, and a light one, LC, of identical size separated by a central partition with a sliding door) display anExpand
Shock avoidance by discrimination learning in the shore crab (Carcinus maenas) is consistent with a key criterion for pain
TLDR
Whether shore crabs placed within a brightly lit chamber learn to avoid one of two dark shelters when that shelter consistently results in shock is examined. Expand
Operant Conditioning in the Crab
TLDR
The eye elevation system of the green crab can also be used in a yoked procedure using air puff to the eye as punishment and a delay introduced between response and punishment reduced the suppressing effect of the punishment. Expand
A Multidisciplinary Approach to Learning and Memory in the Crab Neohelice (Chasmagnathus) granulata
TLDR
A number of important contributions to the field of learning and memory yielded by investigations carried out over more than 20 years in the crab Neohelice (until recently Chasmagnathus) granulata are described. Expand
No discrimination shock avoidance with sequential presentation of stimuli but shore crabs still reduce shock exposure
TLDR
There was no discrimination shock avoidance with sequential presentation of stimuli but, consistent with pain, shore crabs used other tactics to reduce shock exposure and this behaviour is only partially consistent with the idea of pain. Expand
Context-Dependent Passive Avoidance Learning in the Terrestrial Slug Limax
TLDR
An experimental paradigm for quantification of slug's negative phototaxis behavior is developed, and the capability of the slug to form context-dependent passive avoidance memory that can be established in a single conditioning session is demonstrated. Expand
Operant avoidance learning in crayfish, Orconectes rusticus: Computational ethology and the development of an automated learning paradigm
TLDR
It is demonstrated that crayfish successfully learn to respond to spatially contingent cues, and a new computer framework for the automated control of learning paradigms is introduced, based on routines contained within the JavaGrinders library, which integrates real-time video tracking with robotic interfaces, and provides a suitable framework for implementing automated learning Paradigms. Expand
Aversive operant conditioning alters the phototactic orientation of the marbled crayfish
TLDR
Long-term alternation of phototactic behaviour in the marbled crayfish by aversive operant conditionings is mediated by new protein synthesis through the cAMP/PKA/CREB signal cascade, which shows that newprotein synthesis was necessary to form long-term memories. Expand
Gender differences, responsiveness and memory of a potentially painful event in hermit crabs
Nonreflexive responses to a noxious event and prolonged memory are key criteria of a pain experience. In a previous study, hermit crabs, Pagurus bernhardus, that received a small electric shockExpand

TLDR
The method provides an opportunity to study sensory performance and memory consolidation in cockroaches and reversed the initial preference for vanilla over menthol by retraining. Expand
Effect of morphine and naloxone on a defensive response of the crab Chasmagnathus granulatus
TLDR
Male crabs (Chasmagnathus granulatus) exhibited a defensive response to an electric shock and morphine-HCl produced a dose-dependent reduction of the crab's sensitivity to the nociceptive stimulus, suggesting that MP acts through an opiate receptor. Expand

TLDR
The results indicate that memory phases which have different susceptibilities to disruption can be observed in cockroaches. Expand

TLDR
In conditioned animals, identified interneurons of the central pattern generator for feeding behavior, the Int-2s, respond to a food stimulus with greater and more long-lasting excitation than controls. Expand
Opiate receptor in praying mantis: Effect of morphine and naloxone
TLDR
Results of the present paper show that the DR could be also elicited by an actual noxious (an electrical shock) and that this response is similar to that eliciting by a potential nociceptive stimulus (a patterned visual stimulus). Expand

The stinging response of the honeybee: Effects of morphine, naloxone and some opioid peptides
TLDR
Whereas the D50 of morphine for honeybees is far greater than that for vertebrates, the doses of naloxone that antagonize morphine are similar for bees and vertebrates. Expand
Species-specific danger signals, endogenous opioid analgesia, and defensive behavior.
TLDR
The studies are consistent with the view that stress odors and handling stimuli are danger signals that activate endogenous opioid analgesia as well as defensive behavior, suggesting that analgesia is a component of the rat's defensive behavior system. Expand
One-trial associative learning modifies food odor preferences of a terrestrial mollusc.
TLDR
Evidence of rapid and reliable associative learning by the terrestrial mollusc, Limax maximus, is presented and it is shown that exposed slugs displayed a markedly reduced preference for the odor paired with quinidine. Expand

TLDR
A radioimmunoassay has been used to measure Met-enkephalin-like immunoreactivity in tissue from male and female locusts, Schistocerca gregaria, and the results are discussed in relation to recent evidence that peptides related or identical to enkephalins are present in invertebrates as well as higher organisms.
