Japan researchers with determination of brain blood flow instrument, for the first time confirmed the baby was born 5 months later recognize the face.
Japan Central University, researchers rely on near-infrared reflectance spectroscopy to complete this study. This instrument through the body, projected infra-red brain activity associated with the determination of the oxygen consumption and decrease of hemoglobin changes, thus analyses the various parts of the brain activity.
Researchers put the instrument to the 10 5 to 7-month-old baby's head, then let the seven boys and 3 girls watching a screen showing the images. Image playback order first vegetable photos and stay for 10 seconds, then facial photos 5 seconds, then is the vegetable photos 10 seconds, and finally the upside of facial photos 5 seconds, so constantly repeated. At the same time, the researchers also on infant brain 24 areas of oxygen consumption.
Research has confirmed that, in recognition of facial, brain right half of the temporal lobe plays an important role. In this new experiment, the researchers observed that 10 baby watch facial photos, their brain right temporal lobe in the amount of hemoglobin to they eye vegetable photos and reversed facial pictures of 3 times.
Participation in the study of Prof. persimmon wood long medium, when the baby before people can recognize Elli face has, but it is difficult to prove. New study results show that the 5-month-old baby, the face is different from other things special things. This objective determination of baby capacity is an important conclusion.
