　　According to animal experiments in the United States, once the body is about to lose balance, an area of the brain called the "extra vestibular nucleus" helps to regulate muscles and joints, stabilize the center of gravity and maintain body balance.

　　Previously, the scientific community believed that multiple brain regions are involved in maintaining body balance, but which region is responsible for responding immediately after an imbalance? A study published in the new US edition of "Cell Reports" showed in mouse experiments that the lateral vestibular nucleus of the brain stem has this function.

　　The researchers let the mouse walk on the balance beam, then shake the balance beam and observe the mouse's response. We found that when the mouse's body is about to lose balance, it will stretch out its legs to increase the distance between the legs, stabilize the center of gravity, adjust the joints and muscles, and return to the center of the balance beam. When used

　　When

　　brain monitors the mouse brain, walking on a narrow road such as a balance beam will activate the vestibular nucleus area. On the contrary, when walking on a road that is easy to maintain a stable state, the brain area will become dormant. I found it in state. However, when the current lateral nucleus cannot be used due to brain damage or other reasons, it is difficult to maintain the balance of the mouse.

　　Scientists say that when the subway suddenly stands up, the human body still has a similar reaction ability. This study shows that these reflexes work under the guidance of the brain's lateral vestibular nucleus and play an important role in maintaining body balance.
