On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
The neuromodulator dopamine is believed to play multiple roles in decision making, but the neurocomputational basis of dopamine’s influence on behavior remains unclear. Through a combination of fMRI, pharmacology, and smartphone-based experiments in the general population and in Parkinson’s disease, we find evidence that dopamine is associated with increased risk taking in a manner that does not depend on value. Surprising sounds are associated with dopamine release, and we find that surprising sounds increase risk taking in a manner that does not depend on value. Dopamine is also believed to influence willingness to exert effort. We introduce a new task to study the vigor with which actions are taken to obtain reward and the relationship between vigor and mood. We use a combination of lab, online, and smartphone-based experiments to quantify the relationship between reward, mood, and vigor across the lifespan.
