Mary Beckman in his article “Motherhood is a Drug” in the website ‘Science Now’ presented the importance of mother care by showing the result of the experiment of the similarity between suckling and cocaine injection on rats. The similar look of the brain between suckling mother rat and unmarried rat simulated by the drug illustrated that nurturing is a gift of nature and there is a strong bondage between mother-child. Prior experiment of the rats with injured brain or impeded neurotransmitter also identified the same rewarding function, which was proven by Craig Ferris who examined the effect of lactation and drug injection through MRI. This finding reviewed a new mechanism in neuroscientific field, which gives access to the possible connection of humans and rats.
