神经代码似乎通常是根据它们必须携带的信息类型量身定制的。在这里，我们对比了电鱼中两种不同通信信号的编码策略，并描述了实现它们的底层细胞和网络属性。我们将需要快速检测的攻击性信号与需要评估其质量的求偶信号进行比较。干扰信号由同步突发编码，预测反馈输入对于将背景噪声与通信信号分离至关重要。求偶信号通过异质群体响应进行准确编码，从而可以区分信号差异。最重要的是，我们表明其他系统中也使用了相同的策略，认为它们由于面临相似的任务而演化出相似的解决方案。
Neural codes often seem tailored to the type of information they must carry. Here we contrast the encoding strategies for two different communication signals in electric fish and describe the underlying cellular and network properties that implement them. We compare an aggressive signal that needs to be quickly detected, to a courtship signal whose quality needs to be evaluated. The aggressive signal is encoded by synchronized bursts and a predictive feedback input is crucial in separating background noise from the communication signal. The courtship signal is accurately encoded through a heterogenous population response allowing the discrimination of signal differences. Most importantly we show that the same strategies are used in other systems arguing that they evolved similar solutions because they faced similar tasks.
