**Technologies in animal models of visual perception** **Vincent Bonin**<br/> *NERF, VIB, KU Leuven, Belgium* **Francesca Pibiri, Els Crijns**<br/> *Laboratory of Biological Psychology, Department of Brain and Cognition, KU Leuven, Belgium* **John Arsenault, Qi Zhu, Anna Bognar, Francesco Fabbrini, and Rufin Vogels**<br/> *Laboratory of Neuro- and Psychophysiology, Department of Neurosciences, KU Leuven, Belgium* Most of our understanding of the neural processes underlying visual perception comes from invasive studies in animal models of visual perception. We will describe state-of-the art techniques that are used to study neural mechanisms of vision in mammals. The tutorial will provide technical details on the methodology by speakers who are performing the actual research. Participants will obtain a more detailed understanding of the methods, which will assist evaluation of this literature, and the tutorial also will serve as training for students who are planning to use (some of) these methods. We will cover techniques to study vision in rodents, including two-photon Ca2 imaging, visual behavior and electrophysiology. The remaining parts will deal with methods to study visual processing in nonhuman primates (rhesus monkeys) and will include single unit electrophysiology, electrical microstimulation, optogenetics, high resolution fMRI and analysis techniques to uncover homologies of the cortical organization of humans and nonhuman primates.
