Symposium 23: Neuroethology of Social Insects
Recent advances in neurobiology have changed the way we view the central nervous system and how it regulates behavior. One novel and key perspective is an emphasis on neural plasticity- how changes in neuronal structure and function constrain behavior, and how the brain changes in response to even short-term environmental variation. Eusocial insects have served as important models in the plasticity revolution, and continue to offer opportunities to explore neural plasticity in an evolutionary context. The aim of this symposium is to explore how brain plasticity is related to complex, naturalistic, and evolutionarily relevant behavior in insect societies. Social insects offer a special opportunity to explore mechanisms of both individual, and higher-order (group), behavior. They exhibit a wide range of social complexity, inviting comparative analysis.
