As a result, alcohol - exposed worms stop wriggling — the C. elegans version of the sluggish, uncoordinated behavior characteristic of inebriated humans.

With further experimental analysis, the scientists identified two distinct genetic variants that resulted in these sensitivity differences, suggesting that in crowded places, wild C. elegans populations with a specific genetic variation adopt different behaviors than those who don't.

In the wild, C. elegans worms in the quest for food alternate between an exploratory behavior called roaming and a less active behavior called dwelling, where the worms essentially «hunker down and eat,» Bargmann says.

To overcome this technical limitation, we will study the mating behavior of a simple animal, the tiny roundworm C. elegans.

C. elegans is a lab - friendly model species for research on how chemical signals affect development and behavior.

Professor Bargmann then embarked upon what was to become a lifetime mission to define how genes and the environment influence behavior by dissecting the neural circuitry of C. elegans and the genes, receptors, and signaling molecules involved in such behavior as feeding and responses to odors.

Caenorhabditis elegans, a worm with just 302 neurons, shows considerable sophistication in its behaviors, and its defined neuronal wiring and genetic accessibility make it an ideal subject in which to study these interactions.

As a postdoctoral fellow in Dr. Cori Bargmann's lab at the Rockefeller University, she showed that the nematode C. elegans produces a neuropeptide that is an evolutionary precursor of the mammalian peptides vasopressin and oxytocin, and mapped a neural circuit by which this molecule, nematocin, modulates mating behavior.
