Maternal mice infected with nicotine, baby mice reduced awareness

A recent study by scientists at the University of Alabama, USA, found during pregnancy if a mother's mouse is infected with nicotine, the hippocampus area of ​​the brain of mother and baby mice will be hurt, through That causes the mouse to suffer cognitive impairment.

Women who smoke during pregnancy will adversely affect their babies.

The scientists conducted experiments by exposing pregnant mice to nicotine, then observing their brain status.

The results showed that the reproductive ability of adult stem cells in the hippocampus area of ​​the brain of the mother mouse reduced clearly. This reduced the number of new cells produced by the division of adult stem cells, thereby unable to promptly replenish stem cells for the hippocampus neuralgia of the mother's mouse.

The hippocampus area of ​​the brain is the area of ​​the brain that is important for learning and memory. When the hippocampus neural pathway of the brain is affected by the maternal mouse, it will cause the cognitive ability of the pups to decrease.

According to scientists, experimental results on pregnant mice can help explain why pregnant women smoke during pregnancy, babies born are very likely to show symptoms of behavioral disorders as often. Excessive stuff.
