1 "Exhaust gas"
Anxiety of minors maybe a pot of traffic
What? Air pollution not only hurts the body but also hurts the young mind?
There have been many studies in the past that air pollution increases the risk of respiratory diseases, and this study adds new evidence to the dangers of air pollution. Recently, the University of Cincinnati and the Cincinnati Children's Hospital Medical Center observed the nervous system response of minors and found that traffic accidents can cause anxiety in children.
The team selected 145 children, aged 12 years, and used brain imaging (MRI) to detect changes in the levels of Myo-inositol in their brains at different concentrations of traffic. Inositol Myo-inositol regulates hormone and insulin levels, and its elevation indicates an increase in glial cells, often a preliminary response after noxious stimulation. The researchers found that when exposed to high concentrations of traffic, the level of inositol in the brain is greatly increased. Increased levels of inositol are also closely related to the symptoms of anxiety attacks. In the test group of high-concentration traffic exhaust, the anxiety of children who participated in the test increased by 12%.
The research team said that although the current survey does not fully prove that the clinical cause of anxiety attacks is traffic pollution, it also reminds us that air pollution does have the potential to adversely affect the brain and mood.
2 "Memory"
The first memory is before the age of 2? That is probably not yours
"I remember when I was very young, probably more than a year old, my mother accidentally dropped me to the ground..."
Stop, this is probably your false memory.
Past psychological research on memory shows that it is difficult for people to leave memories before the age of two because the hippocampus that store declarative memory is not mature enough, new neurons are still being generated, and old neurons are reorganized and discarded. Memory for a while can't be kept for a long time.
However, it is not a minority to say that you have memories of two years old. In a study published in Psychological Science, about 40% of the 6,641 testers claimed that the earliest memory was before the age of two.
So how did these earliest "memory" come from?
Researchers say that these memories are likely to come from fictional memories of others telling stories. In the study, half of the memory before the age of two was related to the stroller, and another 30% involved family relationships. This shows that these false memories are likely to be adapted from the stories and descriptions of the family. After hearing the same story several times, we became familiar, and then began to wonder if I really remembered it, and later I became really remembered. This continues to strengthen the memory, and finally, the first memory of fiction is produced.
However, this study also found that false memories can have a huge impact like real memories, and even help us maintain a positive and consistent self-narration and identity, promote benign social interaction, and improve the quality of life.
3 "Pet"
Want a dog? This may be genetically determined
If you say it, you may not believe it. Some people want to raise a dog by nature.
Swiss and British scientists at Uppsala University surveyed 35035 pairs of twins and found that genes have a major impact on people's willingness to raise dogs.
In the 35035 pairs of twins, the researchers compared the disparity in the willingness of dogs between fraternal twins and identical twins. Although fraternal twins share the same living environment, growth background, and partially identical genes, the difference in the idea of whether a pair of twins should raise a dog is much larger than that of identical twins. Identical twins with the same genes always want to raise or not raise dogs. This also shows that the gene has a major impact on whether or not to raise a dog.
The next step for the researchers is to find out which ring in the gene chain is working, which will help us to further understand the history of human domesticated dogs as livestock, and also help animals to study people's mental health.
4 "Social Network"
Po's content on social networking sites can reflect depression levels and anxiety
Hey, can I reveal the depression in my microblogging pictures?
Through the latest AI image recognition technology, Penn Medical School counted more than 4,000 test participants' tweets, and performed image recognition analysis on their 3,200 tweets, and compared them with the 887 users' depression and anxiety levels measured by traditional scales. , Find:
- People who have a tendency to depression and anxiety are more likely to give pictures of dull and low-feeling, especially in gray. Moreover, users with depression tend to be more prominent in this regard than users with anxiety.
- Even if they express negative emotions, these users will choose an expressionless picture instead of a more direct expression of the expression with frown and other expressions.
- Users with a high tendency to depression, their photos are more self-portraits without family, friends or others. There are also few meaningful activity scenarios in the background. These all reflect that depression is often accompanied by a decrease in emotional response, self-expression and the disappearance of mood swings.
The research team said that with the development of image recognition technology, one day we may really be able to identify and prevent depression and anxiety through social network information.
