RealFeedApp Odorant 1-octanol is encoded as both attractant and repellent
Whole-network calcium imaging revealed that 1-octanol acts as both an attractant and repellent, with the integration of these opposing signals controlling locomotion speed and reversals.
- Field
- the brain and neuroscience
- What they did
- Researchers studied how the neurons of the worm Caenorhabditis elegans process the smell of 1-octanol, showing that this odor is encoded combinatorially and can be simultaneously attractive and repellent. The strength of these signals determines how the worm regulates its movements and makes decisions about risks.
- Why it matters
- This helps understand how animal brains process sensory information for survival, allowing them to weigh opportunities and hazards in their environment.
