How a brain receptor turns into oxytocin, dopamine, and felt desire
This is where PT-141 earns its identity. It acts centrally on MC4R-bearing hypothalamic neurons, and animal work points at oxytocin and dopamine as the signals that carry the effect forward.
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.
