Insulin-like Peptides as Agents of Social Change.

ABSTRACT

Many behaviors promote reproduction or food finding. These critical functions of behavior can conflict; successful reproductive strategies can grow populations to the point where food is depleted. In this issue of Neuron, Wu et al. (2019) show how the nematode C. elegans detects crowding to change feeding behavior by coupling pheromone sensing to signaling via insulin-like peptides.
