According to the article “Motherhood is a drug”, new research shows that the results of brain scan of suckling moms and those of virgin rats on cocaine are same. The work shows that mothers are rewarded by nature and this result helps understanding of the mother-child bond in human. Researchers believe that the reward system of the brain is relevant to both suckling and drug stimulation. Craig Ferris of the University of Massachusetts Medical Scholl and colleagues examined the effect of suckling and cocaine use to mother rats. They found that, as the result of analysis of MRI, both groups have same results. Neuroscientist Joan Morrell points out that, through this work, scientists can get a better understanding the system of suckling and drug use in human.
