Summary

A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered how sensory-motor circuits—nerve circuits that turn sensory signals into reflex actions—remain reliable even when some genes or neural connections are disrupted. Using the gentle touch reflex of the nematode Caenorhabditis elegans (C. elegans) as a model, the team found that this essential survival response is not controlled by a single biological component.
