Sensory perception of dead conspecifics induces aversive cues and modulates lifespan through serotonin in Drosophila

Abstract

Different sensory experiences can affect longevity in Drosophila. Here the authors find that exposure of Drosophila directly to dead conspecifics affects longevity via a serotonergic mechanism, and that Drosophila exposed to dead conspecifics also become an aversive stimulus to naïve choosers.
