How a brain receptor turns into oxytocin, dopamine, and felt desire
This is where PT-141 earns its identity. It crosses into the brain, activates MC4R on hypothalamic and limbic neurons, and shifts the oxytocin and dopamine signaling that underlies wanting and arousal.
The unit follows that signal from receptor to behavior, contrasts it once more with the vascular PDE5 route, and explains how one receptor can drive desire in women and erection in men through a shared upstream circuit.
