A team of researchers from the Russian Quantum Center, Skolkovsky Institute of Science and Technology and HSE, has developed a new method of scanning and analyzing the electrical activity of the brain, which is carried out using a super-sensitive solid-state magnetometer. This is reported in a press release of scientific work on Godunuki.rf.
Specialists have created a sensor based on an iron-yttrium grenade film, which has become the first solid-state super-sensitive magnetometer operating at room temperature. This makes it possible to simplify the procedure of magnetoesephalography, which requires an extremely cold liquid helium or, on the contrary, heated to high gas temperature. The new system has high sensitivity and is able to register even the weak electrical activity of the brain.
In the future, researchers plan to study various ways of location of sensors, including a flexible compound fixed around the head, providing the most accurate localization of the electrical activity of the cerebral cortex.
Magnetorencephalography is a method of neurovalization, combining non-invasiveness with high spatial and temporal resolution. These properties make Meg one of the most informative neurovalization tools capable of localizing neural activity and suitable for studying complex functional integration processes.
