Following injury, nociceptive systems become sensitized, leading to heightened pain perception. The evolutionary reason for this phenomenon has been hard to pinpoint. A study in squid now suggests that nociceptive sensitization enhances survival from predators.
受伤后,伤害感受系统会变得敏感,导致痛觉增强。这种现象的进化原因一直难以确定。现在一项对鱿鱼的研究表明,伤害感受敏化能提高躲避捕食者的生存几率。
