Is #FAKE this image with optical illusion a stress test | False or false

The viral message accompanied by a drawing with optical illusion circulates in several countries and in different languages ​​at least since the end of November. It has also been verified by several foreign vehicles, such as the BBC.

Ukrainian graphic designer Yurii Perepadia says that he created the drawing in September 2016 with the help of an image editing program. In the O Globo journal, Perepadia claims that his work was influenced by those of Akiyoshi Kitaoka, a professor of psychology at Ritsumeikan University in Kyoto, Japan, known for his studies on the illusions of the world. optical, which could be at the origin of Dr. Yamamoto. in the viral message.

"It is Akiyoshi Kitaoka who stated that with his visual illusions, it was possible to determine the mental state of a person. I learned and understood how draw illusions of optics with their examples, then I created a variety of moving textures and I wrapped it in shapes: spheres, holes, I even made the cards move, "explains the designate.

The design of Yurii Perepadia began to viralizar in social networks from an article published by the professor of cognitive neuroscience of the University of Milan, Alice Proverbio, on Twitter. At the time, the researcher described the operation of the optical illusion caused by the static image. According to Proverbium, neurons that process color and form become saturated and give space to other neurons responsible for the treatment of movements, which causes the effect.

"V5 (or MT) is the cortical area dedicated to movement processing, while V4 is dedicated to the treatment of colors and shapes (like the pentagon) .V4 neurons are so saturated that the basal / rest rate MT neurons is interpreted as a real sensory signal, "explains the professor on Twitter.

Researched by G1 The teacher claims that the circulating message badociating the image with a test of resistance is a "false news". "It is healthy to see the illusion in the movement, it reflects the way the visual areas interact V4 and V5."
