Doctor said he could bring a person out of coma 17:08

The use of drugs to increase the amount of dopamine in the brain, deep electrical stimulation and focused ultrasound can bring a person out of a coma. About this post LifeScience said UCLA psychology professor Martin Monti.

The doctor explained that coma is a life-threatening condition in which the person is unconscious and does not react to any external stimuli. Coma is caused by brain damage due to inflammation, stroke, or infection.

According to Monty, in order to “exit” the coma, the brain must repair damaged neurons or “expand” certain brain networks to take over the work of the damaged area. However, it is difficult to achieve physical repair of brain networks in this way because in coma, brain activity decreases and communication between brain regions is disrupted.

Use of amantadine, a drug thought to increase the amount of dopamine in the brain, may cause an increase in brain activity. Dopamine is a chemical messenger, or neurotransmitter, that is critical for communication between brain networks. Dopamine is also an important element of networks involved in motor control.

Another method of “eliciting” coma is deep brain stimulation, which involves surgically inserting electrodes deep into the brain to apply electricity to neurons. Such stimulation often targets the thalamus, an area of ​​the brain that plays a role in controlling attention and arousal in the central nervous system.

Monty added that increased neuronal activity can be achieved without surgery using focused ultrasound.

It is stated that such methods of recovery from coma can only “work” if the entire structure of the brain is not damaged. The doctor also explained that scientists know little about the reasons for the sudden and spontaneous return to consciousness. According to the expert, it is not possible to determine which factor could cause an increase in brain activity at a particular moment.

Previous scientists statedHe said head transplants would help people live hundreds of years.
