Scientists discover the hidden brain switch that assigns bees their jobs

Biologists have identified specific neural circuits and the 'doublesex' gene that regulate age-dependent task assignment in honeybee colonies. This discovery explains how colonies maintain organizational efficiency without a central leader.
Scientists have identified brain circuits that help determine which jobs worker bees perform inside a colony. Biologists from Heinrich Heine University D sseldorf (HHU) and the universities in Cologne and Frankfurt/Main found that they could change bee behavior by manipulating a particular gene and selectively reducing activity in certain neural circuits.
