A super-accurate way to study the brain based on quantum technologies has been created

Scientists have developed a method for ultra-precise brain scanning based on quantum technologies: the sensor became the world’s first ultra-sensitive magnetometer that works at room temperature. Researchers from the Russian Quantum Center, the Skolkovo Institute of Science and Technology and the Higher School of Economics spoke about this.

In a new work, the authors have created a supersensitive solid-state magnetometer: it was first used experimentally in magnetoencephalography. It is a technology for measuring the electrical activity of the brain.

The authors note that among the advantages of the new development is high accuracy, since biological tissues are transparent to magnetic fields. The sensor also became the world’s first solid-state supersensitive magnetometer operating at room temperature.

In addition, it can register even weak or deep electrical sources of the brain.

Due to the wide dynamic range, the degree of magnetic protection will decrease, and this will reduce the price of the device and make it more accessible for world medicine.

With the new sensors, given their potentially low cost and reliability, we can hope that in the near future, magnetoencephalography technology will become available to a wider circle of patients, doctors and researchers who will get their hands on a functional brain mapping device capable of localizing sources of neuronal activities and neural networks. This will improve the quality of medical care, the accuracy of diagnostics of a number of neurological disorders, including epilepsy, and will give an additional impetus to research into the mechanisms of the functioning of the brain in health and disease.

The authors of the work plan to experiment with the layout of the sensors for the most effective localization of the electrical activity of the cerebral cortex.

You can read more about development in the international journal Human Brain Mapping.
