Seminar: A/ Prof Eva Naumann

December 5, 2018 @ 16:00 - 17:00

Brain-scale neural circuits for visual motion processing in zebrafish

Wednesday 5 December, 4pm at the Sherrington Library, DPAG/Le Gros Clark Bld



The Cortex Club is excited to host A. Prof Eva Naumann from the Duke University, who will be talking to us about her research on how neural circuits across the entire brain guide behaviour in zebrafish. Please join us on December 5th at the Sherrington Library, located in the Sherrington Building of the Department of Physiology, Anatomy and Genetics.

Prof. Eva Naumann has kindly agreed to meet students and staff individually. If you would like to arrange a meeting please contact Tai-Ying Lee at tai-ying.lee [at] dpag.ox.ac.uk.

Please join us at the pub after the talk, register at https://goo.gl/forms/OHwnmWPegKVnVRg23



The larval zebrafish presents an exciting opportunity to investigate the neural basis of vertebrate behavior at the brain scale.  However, it has been particularly difficult to distill neural circuits from whole-brain measurements of neural activity. By combining detailed psychophysics, anatomy, cellular resolution whole-brain imaging, and circuit perturbations, we establish critical links between brain- and circuit-level descriptions of the zebrafish optomotor response. Specifically, we find diverse neural response types distributed across multiple brain regions and show that to transform visual motion into action, these regions sequentially integrate eye- and direction-specific sensory streams, refine representations via interhemispheric inhibition, and demix locomotor instructions into distinct motor modules. Ultimately, we develop a quantitative whole-brain model that explains the behavior and reduces the space of possible synaptic connections into a few critical dimensions of functional connectivity among identified neural response types. More generally, our methodology illustrates a flexible paradigm for studying diverse brain-scale computations related to individuality and motivational states.
