What implications does this research have for treating musicians with brain diseases?
Of course it is useful.
The above shows that for a violinist like the sick Lin Jiayin, when she plays a piece of music, the hand movements cannot be limited to the movement of the little man in the cerebral cortex.
Although the cerebral cortex can be functionally located and divided into zones that specifically correspond to the body's sensory and motor functions, its function is more like an exchange sample output path, and is not a central system like a car engine that provides original driving force.
As medical research goes deeper and deeper, it is found that the complexity of the brain is beyond imagination. How the various parts work together, where is the real central nervous system, whether it is a single central command or multiple central commands, medicine cannot fully understand it yet.
Ordinary people would probably be very anxious after hearing these words. People outside the industry understand common sense. You say that everything is related. Does it mean that if there is something wrong with the brain, the whole brain must be treated, otherwise how can the disease be cured? Isn't it necessary to first figure out the diseased part before treating it?
The doctor's explanation is not necessary for now, and the medical technology level is not up to the task. For example, when treating a large area of cerebral infarction, current medical means are limited. All clinical treatment plans can only be based on existing medical research foundations, and they solve the scope of medical capabilities. As long as the patient can recover to health through medical means, there is no need to investigate other details.
For a disease like this, we can first think of the brain as a circuit network. No matter how complex this circuit network is, how many centers it has, how many power systems or miscellaneous things it has, or how many relay stations it has, it doesn't matter. The doctor only knows that the tumor has taken up space, which is equivalent to a problem in a section of the circuit network. The doctor acts as an electrician and repairs the faulty part of this section, and repairs the faulty circuit problems in this section at the same time, so that the human body will not continue to have problems after the operation.
As for the means of repair, doctors have only a few ways to do it. Cutting is the most common one, which is to cut off the broken circuit. What will happen to the human body after cutting off these circuits?

Here we can learn from the collateral circulation of blood we mentioned before. The human body has a compensatory function. When this path is blocked, the human body will naturally choose a path that can be used. Unless all paths are blocked, this part of the function will be completely lost. This is why surgery should be performed as soon as possible before the tumor grows too big to be managed. At the same time, the human body has a certain self-repair function. These have all been clinically confirmed.
Before repairing the power grid, how to determine which line is faulty? The doctor can use a tester like an electrician, which is the electrode stimulation method used for the patient in bed 18.
For circuit speculation, the two-dimensional method recommended by Xie is a powerful one. So let's talk about the surgical plan discussed by the doctors before, but this time it is for laymen and requires some effort.
Xie Wanying explained as slowly as possible to the people present who did not understand: "During the operation, we doctors were afraid of damaging normal tissues and fearing that incomplete cutting would lead to tumor recurrence, so we needed a method to accurately locate the scope of the tumor. Since the patient is a musician, her brain tissue is related to music. Therefore, our doctors wanted to use music to further observe and judge her lesions, so as to facilitate the removal of as much tumor tissue as possible during the operation."
