Pathogenic bacteria induce aversive olfactory learning in Caenorhabditis elegans
Article Abstract:
The characteristic feature of the nematode Caenorhabditis elegans to modify its olfactory preferences after exposure to pathogenic bacteria, avoiding odors from the pathogen and increasing its attraction to odors from familiar nonpathogenic bacteria is illustrated. Exposure to pathogenic bacteria increases serotonin which functions through MOD-1, a serotonin-gated chloride ion channel expressed in chemosensory interneurons, to promote aversive learning.

C. elegans odour discrimination requires asymmetric diversity in olfactory neurons
Article Abstract:
Research is presented describing how Caenorhabditis elegans can attain odour discrimination by using distinct olfactory neurons or unique neuron combinations to detect different odours. C. elegans uses one pair of olfactory neurons to sense a minimum of five attractive odours.

Dissecting a circuit for olfactory behaviour in Caenorhabditis elegans
Article Abstract:
The importance of olfactory neurons and interneurons in controlling the food- and odor-evoked behaviour of Caenorhabditis elegans is explained. The described circuit is found to be extremely efficient, general and flexible.
