Tiny worms reveal backup circuits that keep survival reflexes from failing
Scientists have discovered that C. elegans worms maintain essential survival reflexes through redundant neural circuits. This genetic and biological backup system ensures that sensory-motor responses remain functional even when specific neural connections are disrupted.
Why it matters
Understanding these redundant biological circuits provides a model for how nervous systems maintain reliability, which could inform future research in neuroscience and robotics.
