In studies of the most mysterious organof the human brain, another breakthrough is planned that can help doctors with a number of operations and provide significant progress along the path of studying the mechanisms of brain functioning. In the laboratories of the University of Wisconsin University in Madison, the technology of disabling consciousness with the opposite effect was tested, which allowed the body to be brought out of a borderline state that was close to coma to normal wakefulness by means of a point effect.
Researchers report that a specific areaThe brain, called central lateral thalamus (the lateral part of the central nucleus of the thalamus), plays a key role in the new technique of returning the body to normal functioning. In monkeys under anesthesia, stimulation of this area was enough to wake the animals to bring them to normal behavior after waking up. After testing on macaques, scientists are preparing to conduct experiments with the human brain.
The studied area of the brain plays the role of a translatorsignals and data processing. Therefore, scientists are trying to establish how the lateral thalamus affects the process of transition from sleep to a normal state and vice versa. For this purpose, a program of point exposure to the thalamus using electrodes was created.
The experimental monkeys received anesthesia andwere in an unconscious state. After the start of stimulation, the animal woke up almost instantly and behaved completely adequately, without the traditional consequences associated with the action of anesthetics. However, such wakefulness was possible only with constant stimulation of the thalamus, after turning off the electrode, the macaque again fell into an unconscious state.
It is assumed that if the stimulation effecthuman thalamus has similar consequences, then such a discovery will advance not only theoretical science, but will also help in practical medicine. So the anesthesiologist will be able to avoid mistakes during anesthesia of the patient with prolonged operations. In addition, the technique will help in the process of removing a person from a coma.
