Success is just a matter of attitude.
Two Spanish scientists gave a new interpretation to the mysterious smile of Mona Lisa using neurological and optical analysis. Autumn’s Most Terrific links of london Tendency The two scientists’ latest study showed that Mona Lisa Smile was caused by visual errors. The reason for whether she smiled or not sometimes was that when we watched her, eyes conveyed different information to the brain.What’s Modish now?links of london Present an Appearance
The famous Italian painter Leonardo da Vinci created the “Mona Lisa” which is the most prestigious portrait in the world. The Right time to Reinstate, The Best links of london to Enjoy The charming smile of Mona Lisa in the picture represents an ancient, dream-like rhyme, it is called “the mysterious smile” by the art historians. Why she was radiant just now, but suddenly looked serious? Mona Lisa’s enigmatic smile confused numerous admirers and researchers.
The scientists of Spain Alicante Nerve Academy of Sciences, Luis Martinez travis Outlaw and Diego Alonso Pabros made a thorough study. They believed that different cells in the retina delivered different kinds of information to the brain or “channels”. These channels would encode the size, clarity, brightness and location of the objects within visual range. Outlaw said, “Sometimes a channel will be covered by another channel and then the smile can be seen, sometimes the channels will be dominated by other channels, and then no smile can be seen.”
To thoroughly analyze her partly hidden and partly visible smile, Martinez Outlaw and Alonso Pablos had the volunteers watch Mona Lisa in different places and angles, and then got to know the changes in the smile they saw to made research into different vision channels.
At first, they asked the volunteers to see the picture in the different distance, but it was difficult for the volunteers to distinguish her facial expression from the far distance as a result of tiny picture. With shorter and shorter distance, the image became bigger, they began to see the smiles – the larger the portrait is, the easier the smile is seen, which shows that both the central vision and peripheral vision cells are able to convey the interpretation of the smile.
Then, they made a comparison to see if the light has impact on the Mona Lisa 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 the volunteers to stare at the white screen and the black screen for 30 seconds respectively, and then let them watch the Mona Lisa portrait. It is easier for volunteers who have watched the white screen before to see Mona Lisa’s smile, because white screen reduced the scattered cells, so Outlaw concluded, one can perceive Mona Lisa’s smile through accumulating cells. This is of course not all the conclusions of the study because the volunteers’ eyes can not help but move to her left cheek right after they distinguished her smile. This indicates that peripheral vision was also involved.
Could it be that Leonardo da Vinci tried to give viewers additional distress, rather than provide inspiration for scientists? Outlaw said, “This is for sure. He has written in the diary that he wanted to paint down various expressions, since they could really reflect people in his mind.”
This is certainly not the first time scientists have tried to interpret the masterpiece of Leonardo-da Vinci. In 1993, the Canadian art historian Susan – Giroux published a shocking research result, she said that the lips of Mona Lisa which dumped by numerous viewing, is the bare spine of a man. American Maryland Dr. Joseph – Bao Stokowski said, “Mona Lisa does not fundamentally smile, and her facial expression clearly shows that she wants to cover the fact that she does not grow front teeth.” The neurosurgery expert Dr. Jacques Kong Daite from Lyon, France, belives that when Leonardo da Vinci made a portrait of Mona Lisa, she had just got a stroke, and half of her face muscles were relaxed, so that she appeared to smile. 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.
