Social Neuropeptides in Nematodes

摘要

The neuropeptides oxytocin and vasopressin stimulate maternal, reproductive, aggressive, and affili-ative behaviors in mammals. They are implicated in behaviors ranging from ewe-lamb bonding in sheep to pair bonding in voles (see the Perspective by Emmons). Now, Garrison et al. (p. 540) and Beets et al. (p. 543) extend the evolutionary reach of these social neuropeptides to the invertebrate nematode worm, Caenorhabditis elegans.
