OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Depth perception is essential for visually-guided behaviour. I will present evidence that neurons in the mouse primary visual cortex are tuned to depth of visual cues derived from motion parallax, generating a depth map of visual space. This depth selectivity is a product of conjunctive coding of visual and self-motion speeds. Depth-selective neurons can be characterized by three-dimensional receptive fields, responding to specific virtual depths and retinotopic locations. I will also present ongoing work exploring the microcircuits underlying these computations using BRISC (Barcoded Rabies in Situ Connectomics), a new high-throughput circuit tracing technique.
SPEAKER BIOGRAPHY
I did my PhD with Tony Zador at CSHL studying circuit mechanisms of decision-making in rats, in particular the role of corticostriatal connection. I then moved to the University of Basel (and later to UCL) to do a postdoc with Tom Mrsic-Flogel, focusing on cell-type-specific microcircuits in the visual cortex. In 2020, I started my lab at the Francis Crick Insititute. My lab studies how different cell types in V1 are wired together to support computations underlying vision, combining systems and molecular neuroscience approaches.
