Hungry for Knowledge: Octopamine Signaling Regulates Hunger‐Enhanced Olfactory Learning
Advanced Science, EarlyView.Researchers demonstrate that hunger state facilitates both aversive and appetitive olfactory learning. Two distinct octopamine signaling pathways are involved in aversive or appetitive memory formation in the hunger state. And, hunger state also facilitates the formation of both types of memories via an evolutionarily conserved norepinephrine (the ...
