The strange hat measured from the field in the human brain

This hat is used in medicine, replacing the MEG weighs half a ton - magnetic field measuring device in the brain.

The device was built by scientists at University College London (UCL) and University of Nottingham (UK). It looks like a strange helmet in a science fiction movie. And like fantasy films, it can capture the exact magnetic field of the volunteers who participated in the experiment.

Volunteers were playing ping-pong while measuring from the brain - (photos provided by the research team).

The hat is a refined and modern miniature version of the traditional MEG machine , which is a half-ton system and needs room for storage. They are commonly used to measure magnetic fields in the human brain, which serves to diagnose brain diseases such as neonatal seizures in children and children, Parkinson's disease.

However, with traditional MEG machines, many cases can not be measured by the physician because the machine requires the patient to remain completely motionless. A 5 mm displacement also damages the image. Getting a newborn baby, young child or a motor disorder patient lying motionless enough to measure is a dilemma.

With this hat, the quantum sensors are very light and are kept close to the scalp so all patient movements do not affect the results of the imaging diagnosis.

In addition, the traditional MEG machine requires a cumbersome chill machine, as many of its components require a constant temperature of -269 ^° C. at room temperature.

According to Gareth Barnes, head of research at the UCLA Wellcome Trust, the ability of patients to move normally while measuring magnetic fields in their brains helps professionals capture brain images. When they are working, they are moving, not just as static as the traditional way.
