- Title
Chemosensation: A behavioural U-turn.
- Authors
Welberg, Leonie
- Abstract
The article discusses the innate preferences for odors encoded in worms. It notes that sensory neurons in Caenorhabditis elegans worms can drive both attraction and repulsion behavior in response to the same stimulus. The AWA and the AWC neurons are two pairs of olfactory neurons that sense odors to which C. elegans is attracted and three other pairs sense odors that it avoids. However, it was noted that attraction and avoidance behaviors can also be reversed when there is butanone exposure.
