Unlike popular myths, scientists from the Massachusetts Institute of Technology found that the brain was absolutely not divided into “logical left” and “creative right” hemisphere. However, in the perception of visual space, each hemisphere continues to operate the opposite side of the field of view. Research Results published In Neuropsychologia.
Professor Earl K. Miller, one of the authors of the study, says, ız There is no scientific justification for the conversation of someone with the right or left hemisphere. You think with the whole brain, ”he says.
However, in the perception of visual stimuli, neurons are active asymmetrically: the left side of the brain is responsible for the right and right of the view. According to Miller, such a division avoids “blind regions ve and increases the effectiveness of perception.
Traditionally, although it is already believed that information is combined with a single picture at the prefrontal cortex level, even scientists have found that there was a displacement in the direction of the “Contraalateral” hemisphere – the opposite of the source of the visual signal. This is confirmed by brain activity measurements: the gamma-band waves are increased in the hemisphere that operates the corresponding part of the field of view.
Earlier studies showed that people and animals recall objects better when they are distributed among the sides of the field of view, which scientists call it “bilateral advantage. However, it is not perfect: a person can only monitor one object on both sides.
However, despite such a functional separation, it is not difficult for people to observe an object that moves from one part of the field of view to another. As the authors explain, the brain quickly “transfers iyle quickly, as the signal transitions between basic cellular stations, quickly“ transfers ”. This provides a continuous and integral perception of the world.
