A new model for the evolution of honey bee brains
by University of Tokyo The researchers studied honey bees exhibiting different behaviors: foragers, nurse bees, and queens. Honey bees in general have been a key insect model for better understanding learning and memory for more than 100 years. Credit: Hiroki Kohno Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part of the insect brain involved in learning, memory and sensory integration) of "primitive" sawflies and sophisticated honey bees.
