Behavior Visual Classical Conditioning in Wood Ants A. Sofia D. Fernandes1,2,3, C. L. Buckley1,3, J. E. Niven2,3 1Department of Informatics, University of Sussex, 2School of Life Sciences, University of Sussex, 3Centre for Computational Neuroscience and Robotics, University of Sussex We present a protocol for the classical conditioning of harnessed ants that permits researchers to study visual learning and memory formation at a level of analysis not possible with freely moving individuals.
