Hugs and physical touch is gentle caring of a mother can be called trigger chemical changes in the brain. Change is in the form of increased levels of interleukin 10, which is a molecule in the brain that inhibit the effects of various types of drugs.
To prove it, researchers from Duke University and the University of Adelaide in Australia doing some experiments on rat pups and its mother. Experiments conducted on researchers used a technique called handling paradigm.
Some rat pups were separated from the parent cage for 15 minutes, then returned again. This treatment makes the parent ikus moved to approach her, sniffing and involved physical contact is more intense than that never separated.
In subsequent experiments, the children are separated again and the rat was placed in an enclosure that has two rooms. Children are free to choose rats want to come in the room, then be injected morphine if it chose to go into one room that has been marked.
In recent times the experiment, rat pups that rarely sniff-sniffing iduknya tend to return to the room with the morphine though it was never given morphine again. This trend shows symptoms of addiction, which is not found in young rats that often sniff-sniffing mother.
Although only demonstrated in mice, a similar mechanism is believed to also occur in humans if not impossible to prove in the same way. Ethically, it is inhumane to separate the child with his mother and then injected morphine dengna just to see how the effect.
But researchers say, molekuol interleukins are also found in the human brain and the levels are influenced by emotion and affection. Quoted from Dailymail, Friday (12/09/2011), these molecules inhibit the emergence of a sense of fun and addictive effects of drugs.
