Individual entities across levels of biological organization interact to reach collective decisions. In centralized neuronal networks, competing neural populations commonly accumulate information over time while increasing their own activity, and cross-inhibiting other populations until one group passes a given threshold. In social insects, there is good evidence for decisions mediated by positive feedbacks, but we found evidence for similar inhibitory signals only in honey bee (Apis mellifera) stop signals, and Pharaoh's ant- (Monomorium pharaonic) repellent pheromones, with only the former occasionally being used as cross-inhibition. We discuss whether these differences stem from insufficient research effort or represent genuine differences across levels of biological organization.
个体在生物组织的各个层次上相互作用，以达成集体决策。在集中式神经网络中，竞争的神经群体通常会随着时间的推移积累信息，同时增加自身的活动，并抑制其他群体，直到一个群体超过给定的阈值。在社会性昆虫中，有充分的证据表明决策是由正反馈介导的，但我们只在蜜蜂（Apis mellifera）的停止信号和法老蚁（Monomorium pharaonic）的驱避信息素中发现了类似的抑制信号，而且只有前者偶尔被用作交叉抑制。我们讨论了这些差异是源于研究投入不足，还是反映了生物组织各个层次上的真实差异。
