A backup circuit in a worm, and what it tells us about nervous systems we cannot see
A research team led from Hong Kong has shown that C. elegans, when its main control neurons are silenced, can still flinch. The worm appears to keep spare circuitry in reserve, and the finding reframes how biologists think about redundancy in the smallest nervous systems.

Desk note: this piece stays close to the published finding and resists the temptation to overstate its clinical reach. Monexus's reading is that the result is most consequential as a model for how redundancy is built into small nervous systems, with downstream implications for how behavioural genetics is done in larger animals.
