Smell of baby addicts as much as drugs, study says

Smell of baby addicts as much as drugs, study says

Feeling the baby smell is a delicious thing, is not it? The moms who say so. Although unintentional, scientists believe there is a physiological explanation for this "mother craze."

According to a scientific study conducted by the University of Montreal, Canada, sniffing a newborn baby intensifies the bond between mother and child, in addition to to increase in women the production of the hormone dopamine, which has a similar effect when one satisfies hunger or when a person who is addicted uses drugs. "What we have identified for the first time is that the odor exhaled by the newborn, which is part of this network of signals, activates in the brain of the rewards area.These circuits can be specially activated in situations of great hunger or even addiction, between a user and the drug, "said researcher Johannes Frasnelli.

To reach the conclusion, the team recruited two groups of 15 women each. The first group consisted of only women without children, and the second group of first-time mothers who had given birth at least a month and a half.

In the analysis, the women had their brain activities measured, by means of magnetic resonance imaging, while each of them smelled using a device called an olfactometer. Among the aromas were pajamas used for two days by infants.

The results showed that the group composed of mothers recorded higher brain activity linked to the rewards area, with a peak in dopamine production, compared to women without children. "What we observe, too, is that not all smells trigger this kind of reaction, only those associated with rewards - like food or desire, for example," Dr. Frasnelli says.

In addition, the study found that odor newborns plays an important role in developing motivational and emotional responses between mother and child, provoking maternal care functions such as breastfeeding and protection.

According to the researchers, this link between mother and child is a consequence of the evolution made through of natural selection, being essential for the survival of the newborn. However, they do not know if this reaction is specific to the mothers, since the men were not part of the experiment.

"It is possible that labor causes hormonal changes that change the reward circuit, but it is also possible that experience of motherhood plays an important role, "concluded the researcher.
