Environmental cues recalling palatable foods motivate eating beyond metabolic need, yet the timing of this response and whether it can develop towards a less palatable but readily available food remain elusive. Increasing evidence indicates that external stimuli in the olfactory modality communicate with the major hub in the feeding neurocircuitry, namely the hypothalamic arcuate nucleus (Arc), but the neural substrates involved have been only partially uncovered. By means of ...

Growth hormone (GH) responsive cells are extensively distributed in the brain, including in neurons of the arcuate nucleus (ARH) and ventromedial nucleus (VMH) of the hypothalamus, areas that control food intake, energy expenditure and blood glucose levels. However, the functional role of central GH signaling for energy and glucose homeostasis has not been unveiled yet. We generated mice lacking GH receptor (GHR) in multiple neuronal populations to investigate whether central ...
