A study of humans and monkeys, published in JNeurosci found that the same subset of neurons encoded the actual and illusory complex motion movement. This finding confirms at the level of individual neurons, what the Czech scientist Jan Purkinje suspected 1
The Pinna-Brelstaff figure is a static image of rings that appear to rotate in a clockwise direction as they move in a clockwise direction and away from a figure in a counterclockwise direction. Having previously identified certain parts of the human brain that represent the Pinna illusion, Junxiang Luo and colleagues from the Institute of Neuroscience confirmed that the Chinese Academy of Sciences initially confirmed that male rhesus macaques are likely to feel the illusion similar to humans , The researchers recorded the activity of individual neurons in the previously identified brain regions and discovered cells that signal the illusory movement similar to the actual movement. A delay of about 15 milliseconds allows the brain to register the illusory movement as if it were real. This study provides new insights into how the brain deals with the constant mismatch between perception and reality.
