Optical silencing of body wall muscles induces pumping inhibition in Caenorhabditis elegans.
Feeding, a vital behavior in animals, is modulated depending on internal Boys Shirts and external factors.In the nematode Caenorhabditis elegans, the feeding organ called the pharynx ingests food by pumping driven by the pharyngeal muscles.Here we report that optical silencing of the body wall muscles, which drive the locomotory movement of worms,
