Russian and American scientists have developed a method of creating a computerized 3D map of the electrical activity of the body, which can be used to detect signs of dangerous cardiovascular and neuromuscular diseases. Procedure using magnetic encephalograph allows you to record and track data in real time. According to experts, the technique will also help in testing of medicines, as it gives the opportunity to see the result of the use of drugs.

Specialists from the Institute of applied mathematics named after Keldysh Russian Academy of Sciences and the medical faculty of new York University have developed a new method of diagnostics of an organism by studying its electrical activity. About that RT has reported in the Russian scientific Fund.

In the method, the scientists subjected the person scanning the magnetic encephalograph. Using this device records the electrical activity of the heart, brain, nervous system and muscles of the patient. On the basis of the evidence creates a three-dimensional mathematical model that helps to identify various disorders in the body.

With this method, the scientists recorded the activity of the nervous and muscular system of ten volunteers aged 28 to 76 years. Each of them was required to conduct three seven-minute session in the encephalograph.

As a result of processing of obtained data and subsequent calculations, the researchers created a 3D map of the electrical activity of the body, which is called three-dimensional “functional MRI”. According to scientists, this map can inform the physicians about the signs of dangerous cardiovascular and neuromuscular diseases. Also it can be used for precise localization of the pain patient.

“With our method was able to successfully reconstruct a three-dimensional functional structure of the brain, heart, muscles of the neck and wrists. The obtained 3D-model are in good agreement with anatomical data, and they carry direct information about the electrical activity of the human body,” — said the project Manager, Deputy Director of the Institute of applied mathematics named after Keldysh of RAS Michael Ustinin.

One of the features of this method is the ability to record and track data in real-time. This procedure is noninvasive, meaning it does not damage tissue. As suggested by the authors of the study, it makes this type of diagnosis is useful for testing various drugs, for example medications for epilepsy: the technology of tracking the activities of the brain in real time will allow you to see how decreased the activity of neurons during an epileptic seizure.
