The subfornical organ: a central target for circulating feeding signals.


The mechanisms through which circulating ghrelin relays hunger signals to the CNS are not yet fully understood. In this study, we have examined the potential role of the subfornical organ (SFO), a circumventricular structure that lacks the normal blood-brain barrier, as a CNS site in which ghrelin acts to influence the hypothalamic centers controlling food… (More)
