Hypothesis

Can olfactory receptors be expressed in taste neurons and allow them to sense volatile molecules?

Conclusion

The study shows that transformed taste neurons in Drosophila can respond to odorants as if they were tastants, altering their hedonic value based on the type of taste neuron expressing the receptor.

Supporting Evidence

  • Transformed taste neurons can sense odors at close range.
  • Odorants modify feeding behavior depending on the type of taste neuron expressing the receptor.
  • Electrophysiological recordings showed that taste neurons responded to both sugars and odorants.

Takeaway

Flies can taste smells! When scientists put smell receptors in taste cells, the flies reacted to smells like they were tasting something sweet or bitter.

Methodology

The researchers used electrophysiological recordings to test the responses of transformed taste neurons to various odorants and tastants.

Limitations

The study primarily focuses on a specific set of receptors and may not generalize to all taste or olfactory interactions.
