Fundamentals of pain perception in animals

Pain is mediated by functionally distinctive components. It may involve acute high threshold afferent stimuli (thermal, mechanical or chemically damaged tissue), protracted afferent input (long-lasting hyperalgesia) or low-threshold input (allodynia as related to pain from light touch). Behavioral patterns will be associated with the effects of noxious stimulus on excitatory transmitters. Humane studies using mechanical, […]
