I was inspired by the weekly round -up for Living Well and made it simple. A better newsletter for information and tools designed to join CNN’s life but to improve welfare.

Are you wondering how it was like to be a baby? But no matter how hard you try, you can’t remember the details?
According to a new study, there is no memories of infancy, but cannot be accessible later in life.
This study published in the journal on Thursday scienceIt was divided into two ages by examining 26 infants between 4.2 and 24.9 months. Less than 12 months and 12 to 24 months.
During the experiment Fmri Machine and a series of unique images are shown for 2 seconds. Researchers hippocampus -Appluses part of the brain associated with emotions, memory and autonomic nervous system.
“The hippocampus is a deep brain structure that is invisible in the standard method, so we have to develop a new approach to perform memory experiments with babies in the MRI machine.” This kind of study was previously done. My infant fell asleep a lot. Because they have a lot of shaking, following the instructions, and have a short interest. ”
Dr. Simona Ghetti, a professor of psychology at the University of California, California, who focused on developing memory of childhood, has already showed that many studies have already shown the ability of infants to encode memory, but this latest study is unique in that memory is unique to the activation of the hippocampus. Getty was not involved in this study.
After the delay, the babies showed two images side by side. One of the familiar images and new images before. The researchers pointed out the baby’s eyes moving and pointed out what image was longer.
If the infant spent more time seeing a familiar image, he suggested that he reminded me of memory. Studies may mean that if they do not show their preferences, they have developed less.
Ghetti said in an e -mail, “eye exercise was used in hundreds of studies on infant memory and classification.
After collecting the initial data, the team analyzed the baby’s FMRI scan to see more familiar images longer and compared it with those who were not preferred. Trials were excluded if the baby did not focus on the screen excessively or blinked.
The findings showed that the hippocampus was more active in older infants when encoding memories. In addition, only older infants have been active in activities. Orbital cortexIt plays an important role in memory -related decisions and perceptions.
Dr. LILA DAVACHI, a professor of psychology at Columbia University, said, “One thing we learn about adult memory is that information that we tend to capture and remember is very related to our experiences.” Will.
The reason why memory encoding seems to be stronger in babies for more than 12 months is not yet clear, but the main change in the body will be the result of the body.
Turk-Browne said, “The infant brain is experiencing many crust, language, exercise, and biological changes, including the rapid anatomical growth of the hippocampus.”
Turk-Brown and his team are actively trying to test why the brain cannot search for these initial memories in life, but the brain processing of infants will not be able to receive accurate “search terms” to find the memories stored in the hippocampus in time.
Ghetti encourages children to think about the effects of infants on their children, even if their parents can’t find out that they have experienced at a young age.
The baby is learning a huge amount at this age. Ghetti said that there is a whole language by associated with the meaning. She added that infants also formed expectations around their families and are studying the objects of the world and the world.
Parents often see this learned behavior when singing the same song or reading the same book. What is mentioned is familiar to older children.
“If you use repetition with your baby, a bigger relationship between your parents and your baby will open,” he said.
Ghetti said that as an adult, he could not remember the early memories, but could be true in both neutral and emotional information.
“This can remind parents that infancy is not idle. hour Ghetti said, “Infants are learning a lot.
