Their activation by fasting is key for survival and is thought to be triggered by feedback when energy stores are low. However, we know that environmental cues can also regulate AgRP neurons since cues that predict future food intake rapidly inhibit AgRP neurons, but is the converse true: can the prediction of future fasting rapidly activate AgRP neurons? Here, we show in mice that such rapid fasting activation of AgRP neurons does occur. This rapid activation is driven by excitatory input from paraventricular hypothalamic (PVH) neurons expressing Sim2, which are bidirectionally sensitive to predictions of future energy state. Thus, cognitively processed contextual information conveyed by PVHSim2 neurons strongly activates AgRP neurons. Lastly, chronic silencing of PVHSim2 neurons causes persistent hypophagia. This PVHSim2-to-AgRP-neuron circuit, by anticipating and preventing negative energy balance, provides an important new dimension of hunger regulation.","lang":"eng"}],"keyword":["hunger","hypothalamus","AGRP neurons","neuroscience","metabolism","homeostasis","feeding","food intake","energy balance","appetite"],"publisher":"Elsevier","title":"A hypothalamic circuit for anticipating future changes in energy balance","publication_status":"inpress","day":"03","department":[{"_id":"AmDo"}],"type":"journal_article","date_published":"2026-06-03T00:00:00Z","acknowledgement":"We thank all members of the B.B.L. laboratory for helpful discussions.
