Neural cluster images. Scientists point out that the two newly discovered nerve clusters are located within the spindle of the brain, only half an inch apart. Their reaction to the face is much stronger than that of hands, legs, cars, guitars, bouquets, and buildings.
According to a report in the "Science Journal", when a patient was recently implanted with a short-term implanted electrode in the brain for painless clinical treatment, medical experts at Stanford University in the United States accurately identified two critical nerve clusters. Both clusters play an important role in facial recognition.
Scientists point out that this finding will have practical value in treating patients suffering from face agnosia (that is, the symptoms that cannot recognize the faces of others), and it also reveals why some people in ordinary people are superior in recognizing faces.
According to scientists, these two nerve clusters are located within the spindle of the brain, only half an inch apart. Their reaction to the face is much stronger than that of hands, legs, cars, guitars, bouquets, and buildings.
It is understood that Ron Blackwell, a patient from Santa Clara, California, received medical treatment under the guidance of renowned medical doctor Josef Parvizi of Stanford University. This is the first attempt by Stanford University medical staff to link two image technology methods with brain shocks to study human spindles. The experimental results also demonstrated for the first time that these two clusters, pFus and mFus, have an extremely important role in human facial recognition.
In the treatment for Blackwell, brain shock stimulation requires current to be conducted from one electrode to another electrode that is 1 centimeter away from it, through a small portion of the brain tissue. The size of pFus and mFus accounts for about 1/4 of the spindle, but also at a distance of 1 cm. Coincidentally, the two electrodes implanted by the scientists are located on the damaged centers of the patient's pFus and mFus. Such a high degree of matching makes Paviz apply the shock stimulus directly on both nerve clusters.
Soon, Blackwell’s facial perception of Pavez changed. He said, “You seem to think of someone I’ve met, but it’s a bit different. Maybe you were that person before, but now your whole face is a bit Deformed, just like the appearance of some features of your face is gone."
When the shock stopped, Blackwell immediately saw Pavizi's face turning from distorted to normal. According to Blackwell, when he pFus and mFus were shocked, he saw no distortion in the pictures of other objects in the room. Pavez said: "When the patient saw my face twisted, I was as surprised as he was."
It is reported that the findings have been published in the Journal of Neuroscience published on the 24th of this month. The study is also currently funded from the Stanford University Bio-X Neuroventures project and the National Institutes of Health.
