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
Weight loss leads to an intense motivation to seek and consume food. We are examining the contribution of hypothalamic neurons to homeostatic hunger. Optogenetic activation of hypothalamic AGRP neurons rapidly induces hunger in mice. The motivational properties of AGRP neuron activity as well as in vivo calcium dynamics indicate that these neurons influence hunger responses through a negative valence teaching signal. These studies reveal a key role for AGRP neurons in learning about food. Our findings are consistent with a neuronal basis for negative emotional attributes of weight loss diets.
