The neural network of a nematode C. elegans is well characterised. The sensory layer is at the top of information processing cascade, and communicates downstream to inter- and motorneurons, consequently driving an animal’s behaviour. The gentle touch is known to be mediated by six Touch Receptor Neurons (TRNs) but their role in modulating the locomotion is not recognised. Animals, whose touch cells are non-functional (mec mutants), are lethargic on-food but retain the ability to move normally under sensory arousal. The TRNs have been earlier implicated in optimising the locomotion gate during
