Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
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.
