With a child really "silly three years"?

With a silly three years? Beijing News · new knowledge weekly recently, our family leadership, she forgot the word old throttle forget road. I have taught them, she also repeatedly filled with guilt. That day, she kept a half-day jump out saying: "hum! don't blame me! blame you children go, have a silly three years, my mother said. "Heard these things, I have some doubts: when MOM so it is not easy, as said, the more the more minds should be used so that only you know. In order to give your children the whitewash, also really come up with good data. So, after I returned home immediately launched a literature search of work. Pregnant or affect brain size does not matter, which investigated the "pregnant fool" topic is cross-culture, in English called "babybrain". Several survey found that up to 50%-80% of mother complains of his mind since pregnancy is not so in the future. The most common symptoms include memory decline, secondly there's reading disabilities and attention deficits. Which memory is the most significant decline, doctors even devoted a pregnant amnesia naming it. Scientists also found that the more female, more educated, this complaint. Does the "pregnant silly three years" as the old saying is true? I don't dare to try so hard to conclusions, because memory decline in this kind of thing with so many life factors, not necessarily caused by pregnancy. Also, sometimes their feelings are not too relies on the spectrum. Sure enough, the United States scientists green (LauraM.Glynn) in January of the neuropsychological Endocrinology (Psychoneuroendocrinology ) magazine published an article entitled "born out of a new brain". The author claims to be "the most informative of human pregnancy childbirth and the relationship between the memory", green found 254 maternal and 48 has not a female fertility, phased test their memory. Discovery green, maternal and control group women in series and in the face of the test is not high, but the maternal in term of"listening to the voice note" on the set of tests on Office productivity. The temperature is not the result of the fire might have some scientists feel very surprised, because changes in maternal body is too much, especially hormones is a roller coaster. For example, in the third trimester of estradiol in females is when she is not pregnant menstrual cycle in the highest level of 30 times; at the same time, her body from cortisone is equivalent to a level of depression. This is just the iceberg, more hormone changes I can't mention them all here. These hormones for growth of the fetus and even delivery provides the necessary material protection. But for moms, are not necessarily so wonderful. The impact of these hormones, the pregnant woman's brain capacity even drops-London-Hammersmith (Hammersmith) hospital Otter niche (AngelaOatridge) and colleagues found that women during pregnancy brain capacity is reduced by 4%. Rat mother health, mind and spirit of all this and more make comparison of neural biologists head, because the person is not the object of their ideal. In contrast, they love the little mouse. Little mouse's performance even more support for a three-year "pregnant fool" people's consent. Most of the research findings and the "Virgin" in female rats, pregnant, breastfeeding or even weaned later, female rats in memory and stress tolerance in full floating red. United States University of Richmond (Universityof Richmond) to Hurst (NaomiHester) led by the research team conducted a study. They found through three rounds of experimentation, rat mother catching cricket faster than ever not mating in rats to five times faster. In the classic "cross maze tests", mother female rats in bright branch of time than a Virgin female rats much longer, like dark mouse, that means they are not so "anxiety". From Canada, British Colombia University Galileo Riyadh (liisaa.m.galea) teams of more detailed, they found that rats mother in first after weaning, the brain is responsible for the memory of the hippocampus in the number of nerve dendritic indeed declined, while the second farrowing time increased to more than make the "girl" level. But whether it is the "first delivery" mouse "or" multiparous rats, they ran a labyrinth of skill are higher than the "Virgin of the rat." To this end, the Galileo Noue explained that "first delivery in rat hippocampal neural" dendritic number of decline is a recycling process, which is equivalent to planting of pruning. In fact, these results are also not surprising, as compared to the excellent ..... laid-back girl, mouse mothers face more challenges in life. It must remember where to find food, must be more skilful predator, more rapid return to the nest, better feeding and protection of their baby. If you do not upgrade the equipment, it will not be able to complete the task. Of course, compared with the mouse, human female brain more complex, before becoming a mother has experienced a myriad of complex challenges, this may be the human mother compared with human girl and not shown completely beyond reason. Of course, compared with the mouse, human mother may face more difficulties and troubles, not only from the body and the physiological, more from the cultural and social. I believe that if you wait or have been regularised by father more help home of leading share some, they would not have so often complains of his head is not so. Well, it seems I also reflect on the wall. □ Lean camel (Shandong biological researchers)
