A group of scientists from the University of Sussex in Brighton (UK) built a modular
A device created in the laboratory of quantumUniversity systems and devices, uses supersensitive quantum sensors to capture the smallest magnetic fields to look inside the brain and map neural activity.
The team attached the sensors to the outsidethe participant's skull, next to the visual cortex of the brain. They asked the participant to open and close their eyes at intervals of 10-20 seconds and found the desired signal. This is a very simple action, but it takes the most sophisticated quantum technology to see how it happens inside the brain.

The researchers added that the quantum sensormust be very sensitive to pick up magnetic fields in the brain, which are actually very weak. In comparison, the magnetic field of the brain is a trillion times smaller than the magnetic field of the refrigerator.
“Since our device is unique in that itmodular, and we have shown that modularity works by connecting two sensors together - we now plan to expand this project by creating more sensors to turn it into a whole brain imaging system. This could lead to significant advances in the detection and treatment of neurodegenerative diseases such as Alzheimer's disease, ”the scientists note.
