Honeybees learn to suppress their innate attraction to light in a passive-avoidance task. Bees placed in a two-compartment chamber in the dark learn to inhibit their spontaneous attraction to a blue-lit compartment after receiving mild shocks upon entering that chamber. Learning induces increases in the dopamine receptor gene Amdop1 in a central structure of the bee brain, the mushroom bodies, and a memory that can be retrieved 24 h later. See Marchal et al. (LearnMem 26: 412–423).
