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
I shall describe three approaches to manipulate the activity of neural circuits in closed loop. (i) By modulating illumination intensity as a function of the local field potential we can use optogenetics to achieve dissociable control of the phase, amplitude and frequency of gamma oscillations. (ii) We have shown that viral expression of a glutamate-sensitive chloride channel both suppresses seizures and rescues comorbidities in a mouse model of temporal lobe epilepsy. (iii) By placing a potassium channel under the control of an immediate early gene promoter, we can selectively inhibit overactive neurons without affecting intermingled neurons, a potentially versatile approach to treat disorders of circuit hyperactivity.
