• Recently, researchers from the York University's
  Langone Medical Center said they found a shell
  region in the center of the mammalian brain which
  may be related to the ability to deal with
  multiple tasks. This area is called the thalamic
  reticular nucleus (TRN). The neurons in the TRN
  region are like the "console" to filter the nerve
  to switch the attention of the brain to one of
  the senses, such as the vision, and shield the
  information to divert attention transmitted from
  other senses.

• The results are published in the international
  academic journal Nature.

• In this study, the researchers developed a new
  behavioral experiment, in which transgenic mice
  were recorded to observe the electrical signals
  of TRN neurons, to observe the behavior of mice,
  and laser was to inhibit the neural circuits of
  different regions of the brain. The results
  showed that when animal models of disease were
  focused on a visual flash signal, the activity of
  TRN neurons was decreased, which was consistent
  with the results of TRN neurons in the inhibition
  of human brain signal.

• In contrast, the researchers said that when the
  mice were guided to focus on the sound and the
  neglect of the flash signal, the visual TRN
  neurons would be more active and inhibit the
  visual signal, making the brain's attention
  focused more on the sound. Early studies had
  shown that different TRN neurons had their own
  specific gene expression.

• The latest research shows how the brain works on
  a specific task. The brain takes the neurons of
  the TRN area as the "console" to control the
  information amount that is received by the brain,
  which limits and filters the information we don't
  want to focus on. the researchers said. What's
  more, they will continue study how much
  information to shield from the TRN neurons in the
  "not relevant" information and what kind of
  changes are further found in the disease models.
