OxTalks is Changing
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
A bright future for the tree shrew in neuroscience research
I’m a post-doc at the Max Planck Florida Institute for Neuroscience, working with David Fitzpatrick on the tree shrew visual system.
I want to understand how the visual system becomes perfectly suited to an animal’s specific visual experience. A lot of factors influence visual experience across an animal’s life-time, like the structure of the retina, the environment, and how the animal moves around in its environment. I’ve studied the visual system of mice, cats, and tree shrews, trying to determine how neural connections transform visual inputs. More recently, I’ve started to think about how these transformations are shaped by, and shape, an animal’s specific movement patterns.
I think the most clever, and interesting, path towards understanding the brain includes multiple animals, and leveraging the quirks each one comes with. Over the past couple of years, I’ve worked on establishing the tree shrew as a model of the extrastriate visual system. I found a unique map of the retina in the secondary visual cortex (V2) of tree shrews that overturned a lot of working assumptions about cortical representations of ego-centric visual space. This data helped to make sense of similar strange-looking patterns in ferrets and squirrels and setup some exciting guesses for primates.
