Wearable brain scanner developed
Patients undergoing a positron emission tomography (PET) scan in today’s bulky, donut-shaped machines must lie completely still. Because of this, scientists cannot use the scanners to unearth links between movement and brain activity.
PATHFINDERS
Patients undergoing a positron emission tomography (PET) scan in today’s bulky, donut-shaped machines must lie completely still. Because of this, scientists cannot use the scanners to unearth links between movement and brain activity.
What goes on up there when we nod in agreement or shake hands? How are the brains of people struggling to walk after a stroke different from those who can? To tackle questions like these, Julie Brefczynski-Lewis, a neuroscientist at West Virginia University (WVU), has partnered with Stan Majewski, a physicist at WVU and now at the University of Virginia, to develop a miniaturized PET brain scanner.
The scanner can be “worn” like a helmet, allowing research subjects to stand and make movements as the device scans. This Ambulatory Microdose Positron Emission Tomography (AMPET) scanner could launch new psychological and clinical studies on how the brain functions when affected by diseases from epilepsy to addiction, and during ordinary and dysfunctional social interactions.
