Russian researchers report for the first time an ultra-precise brain imaging tool

A joint team from the Russian Quantum Center, Skoltech and the Higher School of Economics has proposed a new type of ultra-sensitive solid-state magnetometer that operates at room temperature

Compared with other similar techniques used to study the electrical activity of the brain, the high accuracy of magnetoencephalography (MEG) is its key advantage

A team at the Russian Quantum Center (RQC) has developed a new sensor using yttrium iron garnet films

In order to test the actual effect of this new sensor, Skoltek and researchers from the Higher School of Economics conducted an experimental study, measuring a simple brain induction field-the alpha rhythm-which forms a sine in the back of the brain Current

In the future, the team plans to study various sensor configurations, including placing a flexible belt device on the patient's head to ensure maximum efficiency and accuracy in detecting the exact location of electrical activity in the cerebral cortex

"The original concept of the sensor was put forward by Project Engineering Director Pyotr Vetoshko in the mid-1990s

"Compared with the existing system, even the first prototype of the sensor showed higher MEG sensitivity in some cases, coupled with its simplicity and solid-state characteristics, indicating that the system based on this technology has a bright In the future

"Considering the potential low cost and high reliability of the new sensor, we hope that a wider user audience will be able to afford MEG

Of course, there is still a lot of work to be done, including further research on the physical properties of the sensor and the development of a new mathematical signal processing device to ensure the high efficiency of this new specific type of magnetometer," commented by Assistant Professor, Nikolay Koshev Skoltech

"Considering the potential low cost and high reliability of the new sensor, we hope that a wider user audience will be able to afford MEG
.
This means that patients, doctors and researchers will have a functional brain mapping tool that can measure Accurately detect the source of neural networks and neuron activity
.
This will help improve the quality of medical care and the accuracy of diagnosis of various neurological diseases, including epilepsy, and will give new impetus to the study of the operation of the human brain in health and disease "Professor Alexei Ossadtchi, director of the Center for Biological Higher School of Economics, interface, notes
