Carlo V. Bellieni (Siena, Italy, born 1962) is an Italian neonatologist and a bioethicist.
Bellieni authored numerous clinical research papers in international scientific journals,[5][6] and several books on neonatal pain and bioethics.
Bellieni created and developed a new method of nonpharmacological analgesia called "sensorial saturation",[7] based on the simultaneous administration of gentle stimuli (touch, taste and voice) to the baby during a painful procedure.
Weeping induces empathy perhaps with the mediation of the mirror neurons network and influences mood through hormone release elicited by tears’ massage effect on cheeks or through relief from sobbing rhythm.
