近日，美国哥伦比亚大学Federico Pedraja和Nathaniel B. Sawtell合作揭示电鱼的集体感应。2024年3月6日，《自然》杂志在线发表了这项成果。
研究人员通过建模、神经记录和行为实验提供证据，证明非洲弱电鱼Gnathonemus petersii利用同类的电脉冲来扩大电定位范围、分辨物体和增加信息传输。这些结果为一种新的、集体的主动感知模式提供了证据，在这种模式中，个体的感知能力会因附近群体成员的能量发射而增强。
据了解，包括海豚、蝙蝠和电鱼在内的许多生物都拥有复杂的主动感知系统，利用自发信号（如声发射或电发射）来探测环境。对社会群体中主动感应的研究通常集中在如何尽量减少同类发射干扰的策略上。然而，众所周知，在工程学中，多个空间分布的发射器和接收器可以大大提高环境感知能力（例如多静态雷达和声纳）。

Abstract: A number of organisms, including dolphins, bats and electric fish, possess sophisticated active sensory systems that use self-generated signals (for example, acoustic or electrical emissions) to probe the environment1,2. Studies of active sensing in social groups have typically focused on strategies for minimizing interference from conspecific emissions2,3,4. However, it is well known from engineering that multiple spatially distributed emitters and receivers can greatly enhance environmental sensing (for example, multistatic radar and sonar)5,6,7,8. Here we provide evidence from modelling, neural recordings and behavioural experiments that the African weakly electric fish Gnathonemus petersii utilizes the electrical pulses of conspecifics to extend its electrolocation range, discriminate objects and increase information transmission. These results provide evidence for a new, collective mode of active sensing in which individual perception is enhanced by the energy emissions of nearby group members.
