The concentrated brain stops paying attention to things

  Although people’s imagination is infinite, their attention is limited. This is why the teacher repeatedly emphasizes the need to concentrate in class.
  In the last century, a psychologist conducted an experiment. When a ball game was broadcast on TV, when it was the most exciting, suddenly a person pretending to be a gorilla appeared on the camera. After the game was over, the audience was asked if they noticed the “gorilla” on the camera. In all likelihood, the audience said no.
  Recently, a neurological study provided support for this psychological experiment. Neurologists at the University of London asked volunteers to wear a helmet that can measure the activity of neuronal mitochondria. We know that mitochondria are energy factories in animal cells, and the energy that neurons discharge comes from mitochondria.
  Then, the researchers asked the volunteers to do a simple or difficult visual task, such as finding certain shapes and colors on the screen. When searching, a flickering checkerboard pattern is played at the edge of their field of view half of the time.
  The researchers found that when the task is simple (meaning that no full attention is required), neurons that process peripheral vision also increase their firing rate when they flicker in a checkerboard pattern. This shows that in this case, volunteers can complete the task while paying attention to the checkerboard pattern. However, when the task is difficult, although the checkerboard pattern is still flickering, the firing rate of neurons processing peripheral vision does not increase. This shows that in this case, the volunteers did not notice the checkerboard pattern.
  In fact, the “competition” for limited attention not only occurs between the same sense organs, but also between different kinds of sense organs. For example, when a person is tortured by pain, he will not pay attention to what the eyes see and what the ears hear.
