Research

What changes in the brain take place to allow us to learn and remember information? The honey bee, Apis mellifera, is an excellent system in which to investigate the mechanisms of learning and memory due to its outstanding ability to learn and its well characterized neurobiology. Current research focuses on the roles of biogenic amines in learning and memory. The biogenic amines are small intercellular signaling molecules that act as neurotransmitters and neuromodulators. They affect cells via binding to G protein coupled receptors that are expressed on the surface of responsive cells. The biogenic amines and their receptors are highly conserved across species; therefore, studying them in bees can provide insight into how they function in humans. Areas of research include: 1) Understanding the roles that the biogenic amines dopamine, octopamine and tyramine play in learning and memory and other behaviors; 2) Molecular and pharmacological characterization of the biogenic amine receptors; 3) Investigating how drugs of addiction, such as caffeine and alcohol, affect the reward pathways normally controlled by octopamine and dopamine.
