伤害感受是感知有害刺激并以反射方式反应的能力，并且发生在广泛的分类群中。然而，体验相关的厌恶感觉和感觉的能力，称为疼痛，并没有被广泛接受发生在非脊椎动物中。我们研究了十足类甲壳动物，对虾，Palaemon elegans，不同的伤害性刺激施加到一个天线，以评估反射反应（伤害性）和长期的，具体定向的行为反应，可能表明疼痛的反应。我们还研究了局部麻醉剂苯扎林对这些反应的影响。伤害性刺激引起立即反射甩尾反应，随后是两个延长的活动，梳理天线和天线对坦克的侧面摩擦，这两个活动专门针对处理的天线。这些反应被苯并咪唑抑制;然而，苯并咪唑并没有改变一般游泳活动，因此梳理和摩擦的下降不是由于全身麻醉。机械刺激捏也导致延长摩擦，但这是不抑制benzoacetamide。这些结果表明，伤害性刺激的位置的意识，和长期的复杂的反应表明在其组织的中央参与。局部麻醉剂的抑制作用与脊椎动物的观察结果相似，并且与这些甲壳类动物可以体验疼痛的想法一致。(c)2007年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Nociception is the ability to perceive a noxious stimulus and react in a re flexive manner and occurs across a wide range of taxa. However, the ability to experience the associated aversive sensation and feeling, known as pain, is not widely accepted to occur in nonvertebrates. We examined the responses of a decapod crustacean, the prawn, Palaemon elegans, to different noxious stimuli applied to one antenna to assess reflex responses (nociception) and longer-term, specifically directed behavioural responses that might indicate pain. We also examined the effects of benzocaine, a local anaesthetic, on these responses. Noxious stimuli elicited an immediate reflex tail flick response, followed by two prolonged activities, grooming of the antenna and rubbing of the antenna against the side of the tank, with both activities directed specifically at the treated antenna. These responses were inhibited by benzocaine; however, benzocaine did not alter general swimming activity and thus the decline in grooming and rubbing is not due to general anaesthesia. Mechanical stimulation by pinching also resulted in prolonged rubbing, but this was not inhibited by benzocaine. These results indicate an awareness of the location of the noxious stimuli, and the prolonged complex responses indicate a central involvement in their organization. The inhibition by a local anaesthetic is similar to observations on vertebrates and is consistent with the idea that these crustaceans can experience pain.
