n Helmet with Sensors
Records Brain Function
Researchers have designed
a lightweight helmet
with tiny LEGO-size sensors
that scan the brain while a
person moves. The helmet
is the first of its kind to accurately
record magnetic fields
generated by brain activity while people are in motion. This
advance could make it easier to conduct brain scans in young
children and individuals with neurological disorders who can't
always remain still in conventional scanners.
Researchers can use the wearable brain scanner, which can
be adapted to different head sizes and shapes, to learn more
about brain development and what happens in the brains of
children and adults who develop neurological conditions such
as autism, epilepsy, stroke, concussion, and Parkinson's disease.
A new matrix coil system features 48 smaller coils on two panels
positioned around the participant. The coils can be individually
controlled and continually recalibrate to compensate for
the magnetic field changes experienced by the moving sensors,
ensuring high-quality magnetoencephalography (MEG) data
are recorded. (Image credit: Clayton Metz for Virginia Tech)

n Patch Uses Body
Motion for Disc Herniation
A new biologic patch that is
activated by a person's natural
motion could be the key to fixing
herniated discs in people's
backs. The tension-activated
repair patches (TARPs) provide
controlled release of an anti-inflammatory molecule called
anakinra from microcapsules over time, which helped discs in a
large animal model regain the tension they need to reverse herniation
and prevent further degeneration.
Key to the TARP is having the body's natural mechanics
work to activate the release of anti-inflammatory molecules
from the microcapsules within the patch. While they would
theoretically still work if a person lay totally still for months,
the reality of the disc tissue environment is that movement is
its natural state.
And because the patch makes it as if there was never a hole
to begin with, its application could have significant effects on
the prevention of worsening pain related to disc degeneration.
While this research was primarily " proof of principle, " moving
this treatment closer to the clinic will require longer trials in
large animal models. (Image credit: Penn Medicine)
