Almost certainly “forced” by the smile of Leonardo da Vinci’s famous Mona Lisa – said three neuroscience researchers who thought the Renaissance polyhistor deliberately painted the expression of his model.
Lucia Ricciardi and two of her colleagues, Luca Marsili (University of Cincinnati) and Matteo Bologna (University of La Sapienza), at the University of London’s St. George Medical School, first stepped in a vertical line with Mona Lisa’s mouth and mirrored the two sides so they got two types of mouths.

The two images of the two types of smiles received were shown to 42 participants of the research who had to evaluate their facial expressions based on their own impressions. The respondents agreed that the image of the left-hand side of the mouth is a smile, while the image of the right half of the mouth seems less expressive, mostly neutral or sad. Based on these, the researchers found that Mona Lisa’s smile was asymmetric.
“According to the most widely accepted neuropsychological theories, if a smile is asymmetric, it is usually not sincere. In contrast, the sincere, spontaneous, so-called Duchenne smile is symmetrical.
In addition, recent research has suggested that asymmetric smile can be a sign of dichotomy or lying.
“Of course, we know that if a man sits on an image for hours, he will lead to a forced expression,” the specialist said. He added, “at the same time, we know that Leonardo was the master of shielding the sphumato technique used to revive facial expressions. That is, he deliberately lifted the left corner of the model’s mouth as if he wanted to smile while he had to knock the lips on both sides up and down.” wrinkles on the eyes, you get a sincere smile. ”
According to Ricciardi, Da Vinci was aware of the fact that hundreds of years ago, Guillaume Duchenne’s researcher of French origin published his work in the 1800s. “That’s why we assume that this smile has deliberately become asymmetric. But we still don’t know why the master painted it like that, Mona Lisa’s smile is even more mysterious to us than it was before,” the researcher said.
