Hypothesis
Can C. elegans detect and respond to airborne sound?
Conclusion
C. elegans can sense airborne sound and exhibit avoidance behavior in response to it.
Supporting Evidence
- C. elegans exhibits phonotaxis behavior to sounds directed at the head or tail.
- Localized sound can evoke a robust phonotaxis response in C. elegans.
- The sound-sensitive FLP neuron in immobilized worms was activated by sound, but the response was less robust than in freely moving worms.
- Wild-type worms showed robust avoidance of sound, while des-2 deg-3 mutants exhibited a deficiency in phonotaxis response.
Takeaway
C. elegans, a tiny worm, can hear sounds and move away from them, just like we do when we hear something loud.
Methodology
The study involved building a custom sound delivery system and conducting behavioral assays and calcium imaging to assess auditory responses in C. elegans.
Limitations
The study's findings may not be generalizable to other species, and the equipment used may not be widely accessible.
Participant Demographics
The study focused on adult hermaphrodite C. elegans.
