Two Spanish scientists made a new interpretation on Mona Lisa's enigmatic smile through neurological and optical analysis. The two scientists' latest study shows that Mona Lisa's smile is caused by visual errors. The reason why we sometimes see her smile or don't is that our eyes are conveying different information to the brain while we are watching her.How to Protect the Mode of ugg classic cardy ?
Mona Lisa, which was created by the famous Italian painter Leonardo da Vinci is the most prestigious masterpiece of portrait all over the world. The charming smile of the Mona Lisa has a dream-like charm through the ages, which is regarded as the mysterious smile by art historians. Why just radiant face suddenly looked seriously? Many admirers and researchers are confused about Mona Lisa's enigmatic smile.ugg classic cardy Trend You Should Never Ignore
The Spanish scientists of Alicante nerve Academy of Sciences, Luis Martinez Outlaw and Diego Alonso Pabuluosi, studied on it. In their view, the different cells in the retina convey different information or "channels" to the brain. Those channels will ecode the size, clarity, brightness and location of the different objects within your visual range. Outlaw said, "Sometimes a channel will be covered by another channel, then you'll see a smile; sometimes it is dominated by other channels, then you will not see a smile."
To analyse visional smile of Mona Lisa at large, Martinez Outlaw and Alonso Pabulusi made volunteers stand different position and angle to appreciate Mona Lisa and recorded their smile change to study different visual channels.
At the begining, they asked volunteers to see the picture in ever-change distance. In a long distance, the volunteers couldn't see facial expreesion very clearly. The picture became bigger and bigger with gradually shorter distance, they began to see the smile-the more biger picture, the more they can see the smile. This is show that the central visual cells have the same function of conveying smile message as cells in peripheral vision.
Then they compared whether light can affect the observation of Mona Lisa's smile. Two kinds of cells will decide the object's brightness in the environment, one is "concentral cell", it will be stimulated under the condition of only central bright objects and show the bright star in the darkness; the other is called "seperated cell", it will be stimulated by only central dark objects and help us to see the text on the book.
Martinez Outlaw asked volunteers to watch the white screen and black screen respectively for 30 seconds, and then let them watch the Mona Lisa portrait. It was easier for the volunteers to see the Mona Lisa smile after watching the white screen. The white screen reduced the "scattered cells", so Outlaw concluded: "concentrating cells" can perceive Mona Lisa`s smile. This of course was not all the conclusions of the study, because when volunteers told the smile in an instant, their eyes can not help moving to her left cheek, which showed the role of peripheral vision.
Could it be that that da Vinci tried to increase the trouble to the admirers instead of providing the muse for scientists? Outlaw said, "It was absolutely sure. He had written in his note, he would print the expression with extensive changes which were just all mortal beings in his eye."
Of course, this was not the first time for scientists to try to interpret Leonardo - Leonardo da Vinci's masterpiece. In 1993, the Canadian art historian Susan - Giroux published a shocking research results, she said that Mona Lisa's lips fascinating numerous viewers were a man's bare spine. Maryland of the States Joseph- Dr. Bao Stokowski said, "Mona Lisa are fundamentally no smile, her facial expression is very clearly that she wanted to cover up her has no front teeth." Jean Jarques Condette, a brain surgeon from Lyon, France thought that Mona Lisa had just recovered from a stroke. She seemed to smile because half of the face muscles are loose. In 2005, a panel from the US declared that whether we see a smile or other expression can be determined by the disturbing factors on the path from retina to visual cortex.
