This study examined stimulus-response properties of somatosensory receptors on the head of rainbow trout, Oncorhynchus mykiss, using extracellular recording from single cells in the trigeminal ganglion. Of 121 receptors recorded from 39 fish, 17 were polymodal nociceptors, 22 were mechanothermal nociceptors, 18 were mechanochemical receptors, 33 were fast adapting mechanical receptors and 31 were slowly adapting mechanical receptors. Mechanical thresholds were higher in polymodal nociceptors… Expand
Characterisation of chemosensory trigeminal receptors in the rainbow trout, Oncorhynchus mykiss: responses to chemical irritants and carbon dioxide
This is the first time that external CO2 receptors have been identified on the head of a fish and a range of chemical stimulants were applied to determine whether the receptors have a nociceptive function. Expand
Can crayfish take the heat? Procambarus clarkii show nociceptive behaviour to high temperature stimuli, but not low temperature or chemical stimuli
Crayfish showed no difference in behavioural response to low temperature stimuli, and neurons in the antenna did not change their firing rate following application of capsaicin or isothiocyanate, which appears to be a potentially ecologically relevant noxious stimulus for crayfish that can be detected by sensory neurons, which may be specialized nociceptors. Expand
Do Decapod Crustaceans Have Nociceptors for Extreme pH?
There was no behavioural or physiological evidence that the antennae contained specialized nociceptors that responded to pH, and previously reported responses to extreme pH are either not consistently evoked across species or were mischaracterized as nOCiception. Expand
Squid Have Nociceptors That Display Widespread Long-Term Sensitization and Spontaneous Activity after Bodily Injury
It is demonstrated that squid possess nociceptors that selectively encode noxious mechanical but not heat stimuli, and that show long-lasting peripheral sensitization to mechanical stimuli after minor injury to the body. Expand
ermonociception in fish : Effects of two different doses of morphine on ermal threshold and post-test behaviour in goldfish ( Carassius auratus )
The question of whether fish can perceive pain is controversial, and pain is a potentially grave threat to fish welfare. To be able to study pain in a species, knowledge of its nociceptive system isExpand

There is ample evidence to demonstrate that it is highly likely that fish experience pain and that pain-related behavioural changes are conserved across vertebrates. Expand
Thermonociception in fish: Effects of two different doses of morphine on thermal threshold and post-test behaviour in goldfish (Carassius auratus)
An apparatus was developed to expose goldfish to controlled, localised heat stimulation and the hypothesis that goldfish perceive heat as aversive was tested, and all 16 fish responded to the heat with an escape response, with a mean baseline of 38 8C. Expand
Physiological and Behavioural Responses to Noxious Stimuli in the Atlantic Cod (Gadus morhua)
The only effect seen in hooked fish was brief episodes of lateral head shaking which were not seen pre-treatment or in the other groups, possibly reflecting a resiliency to tissue damage in the mouth area related to the tough nature of the Atlantic cod diet. Expand
Effect of noxious stimulation upon antipredator responses and dominance status in rainbow trout
A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or anExpand
Nociceptors: a phylogenetic view
This review will focus on what is known about nociceptors throughout the Animalia kingdom and what similarities exist across phyla; especially at the molecular level of ion channels. Expand


Trigeminal somatosensory innervation of the head of a teleost fish with particular reference to nociception
The trigeminal nerve of a teleost fish, the rainbow trout, was examined to determine what types of somatosensory receptors were present on the head of the trout specifically searching for nociceptors, which had similar physiological properties to nocICEptors found in higher vertebrates. Expand
Do fishes have nociceptors? Evidence for the evolution of a vertebrate sensory system
This study provides significant evidence of nociception in teleost fishes and demonstrates that behaviour and physiology are affected over a prolonged period of time, suggesting discomfort. Expand
Responses of cutaneous A-fiber nociceptors to noxious cold.
It is concluded that the proportion of cutaneous A delta-nociceptors excited by noxious cold stimuli has been underestimated in previous studies and is likely to contribute to the sensation of cold pain, particularly pain produced by stimulus temperatures <0 degrees C. Expand

Mechanical response properties of nociceptors innervating feline hairy skin.
Only the MIAs appeared to have the capacity to unambiguously encode mechanical stimulus intensities above pain threshold, as the group of afferents commonly defined as nociceptors exhibit a heterogeneity of mechanical response properties, which may serve functionally different roles for perception.

Putative nociceptor responses to mechanical and chemical stimulation in skeletal muscles of the chicken leg
The existence of nociceptive sensory fibres in chicken skeletal muscle that are able to respond to and encode acute tissue threatening and subjectively painful stimuli is demonstrated and support the suggestion of a common, acute nOCiceptive response function in skeletal muscle in avians and other vertebrate classes. Expand
Chemosensitivity and sensitization of nociceptive afferents that innervate the hairy skin of monkey.
A large proportion of primate cutaneous nociceptors respond to intradermal injection of algesic/inflammatory mediators and may also become sensitized to mechanical and/or heat stimuli. Expand
Properties of corneal receptors in a teleost fish
The lack of cold sensitive neurons in the rainbow trout may provide evidence for the evolution of cold nociceptors in vertebrates that is related to the transition from poikilothermy to homeothermy. Expand
Mechanothermal nociceptors in the scaly skin of the chicken leg
Comparison of the physiological properties of the C fibres in the legs with those previously identified in the beak showed that those in the leg had significantly lower thermal thresholds, but higher mechanical thresholds, and the possible functional significance of these differences is discussed.
