OXT and craniopharyngioma: Specifically, Daubenbüchel et al. (2016) did not find any significant differences when comparing the change between pre- and post-prandial salivary oxytocin concentrations between craniopharyngioma and controls, with both groups showing similar post-prandial (compared to pre-prandial) decreases in oxytocin concentrations, suggesting that the postprandial oxytocin response is intact in craniopharyngioma.
