Dear Editor,rnFor an animal to explore its environment, the mechanosensots on its head are of particular importance.For example,in Drosophila larvae that constantly explore the surrounding substrate during foraging and wandering, the cephalic segments host highly specialized organs with extraordinary mechanical sensitivity [1].While mechanosensation on the thoracic and abdominal segments has been studied extensively [2], the functions and molecular features of cephalic mechanosensation have not yet been characterized, despite the unambiguous presence of mechanosensors [3].
