TEXTO:
British scientists have developed a lightweight and
highly sensitive brain imaging device that can be worn
as a helmet, allowing the patient to move about naturally.
Results from tests of the scanner showed that patients
[5] were able to stretch, nod and even drink tea or play
table tennis while their brain activity was being
recorded, millisecond by millisecond, by the
magnetoencephalography (MEG) system.
Researchers who developed the device said they
[10] hoped the new scanner would improve research and
treatment for patients who can’t use traditional fixed
MEG scanners, such as children with epilepsy, babies,
or patients with disorders like Parkinson’s disease.
Current MEG scanners are cumbersome and weigh
[15] as much as half a ton, partly because the sensors they
use to measure the brain’s magnetic field need to be
kept very cold - at minus 269 degrees Celsius, Barnes’
team explained. They also run into difficulties when
patients are unable to stay very still — very young
[20] children or patients with movement disorders for
example — since even a 5-millimeter movement can
mean the images are unusable.
In the helmet scanner, the researchers overcame
these problems by using quantum sensors, which are
[25] lightweight, work at room temperature and can be
placed directly onto scalp — increasing the amount of
signal they are able to pick up. Moreover, the wearable
scanner offers new possibilities ∈ measuring peoples’
brain function during real world tasks and social
[30] interactions. “This has significant potential for impact
on our understanding of not only healthy brain function
but also on a range of neurological, neurodegenerative
and mental health conditions.”

Fill ∈ the parentheses with T (True) or F (False).
About the brain scanner mentioned ∈ the text, it’s correct to say:
( ) It looks like a hard \hat.
( ) It’s much like traditional fixed MEG scanners.
( ) It limits most of the patient’s movements.
( ) It registers brain activity accurately even when you aren’t still.
