Increased expression of neuropeptide receptors is shown for oxytocin. A: Binding of an iodinated selective analogue to oxytocin receptors is evident in several regions of neocortex in the one day old marmoset. B: Under identical conditions, binding of the same ligand is not detectable in cortex, but appears in the ventral pallidum at the same level of the adult marmoset brain. ac, anterior commissure.
