How the GyroGlove Steadies Hands of Parkinson’s Patients

How the GyroGlove Steadies Hands of Parkinson’s Patients | Social Neuroscience Advances | Scoop.it
A wearable device promises to help steady hand tremors by using an old technology—gyroscopes.


When he was a 24-year-old medical student living in London, Faii Ong was assigned to care for a 103-year-old patient who suffered from Parkinson’s, the progressive neurological condition that affects a person’s ease of movement. After watching her struggle to eat a bowl of soup, Ong asked another nurse what more could be done to help the woman. “There’s nothing,” he was grimly told.


Ong, now 26, didn’t accept the answer. He began to search for a solution that might offset the tremulous symptoms of Parkinson’s, a disease that affects one in 500 people, not through drugs but physics. After evaluating the use of elastic bands, weights, springs, hydraulics, and even soft robotics, Ong settled on a simpler solution, one that he recognized from childhood toys. “Mechanical gyroscopes are like spinning tops: they always try to stay upright by conserving angular momentum,” he explains. “My idea was to use gyroscopes to instantaneously and proportionally resist a person’s hand movement, thereby dampening any tremors in the wearer’s hand.”


Together with a number of other students from Imperial College London, Ong worked in the university’s prototyping laboratory to run numerous tests. An early prototype of a device, called GyroGlove, proved his instinct correct. Patients report that wearing the GyroGlove, which Ong believes to be the first wearable treatment solution for hand tremors, is like plunging your hand into thick syrup, where movement is free but simultaneously slowed. In benchtop tests, the team found the glove reduces tremors by up to 90 percent.


GyroGlove’s design is simple. It uses a miniature, dynamically adjustable gyroscope, which sits on the back of the hand, within a plastic casing attached to the glove’s material. When the device is switched on, the battery-powered gyroscope whirs to life. Its orientation is adjusted by a precession hinge and turntable, both controlled by a small circuit board, thereby pushing back against the wearer’s movements as the gyroscope tries to right itself.


While the initial prototypes of the device still require refinements to size and noise, Alison McGregor, professor of musculoskeletal biodynamics at Imperial College, who has been a mentor to the team, says the device “holds great promise and could have a significant impact on users’ quality of life.” Helen Matthews of the Cure Parkinson’s Trust agrees: “GyroGlove will make everyday tasks such as using a computer, writing, cooking, and driving possible for sufferers,” she says.

Predicting Who May Develop Alzheimer’s, and Who May Not

Predicting Who May Develop Alzheimer’s, and Who May Not | Social Neuroscience Advances | Scoop.it
Investigators have wondered why the brains of some cognitively-intact elderly individuals have abundant pathology on autopsy or significant amyloid deposition on neuroimaging that are characteristic of Alzheimer disease (AD). Researchers reporting in the American Journal of Pathology investigated biochemical factors and identified differences in proteins from parietal cortex synapses between patients with and those without manifestation of dementia. Specifically, early-stage AD patients had elevated concentrations of synaptic soluble amyloid-β (Aβ) oligomers compared to controls who were not demented but displayed signs of AD pathology. Synapse-associated hyperphosphorylated tau (p-tau) levels did not increase until late-stage AD.

 

"Investigators examined whether synaptic Aβ levels were associated with neuritic plaque levels in the parietal cortex. They found little or no evidence of Aβ immunolabeling in either of the control groups but observed a rise in synaptic Aβ concentration associated with increasing neuropathologic disease stages. Synaptic Aβ levels highly correlated with the occurrence of plaque. Image is for illustrative purposes only."

How Our Memories Guide Attention

How Our Memories Guide Attention | Social Neuroscience Advances | Scoop.it
A team of researchers has discovered that differences in the types of memories we have influence the nature of our future encounters. Their findings show how distinct parts of the brain, underlying different kinds of memories, also influence our attention in new situations.

“We’ve long understood there are different types of memories, but what these findings reveal are how different kinds of memories can drive our attention in the future,” explains Elizabeth Goldfarb, the study’s lead author and a doctoral candidate in NYU’s Department of Psychology.

It’s been established that the types of memories we have include episodic memories—characterized by our recollections of the contextual details of life events, such as remembering the layout and location of objects in a familiar room —as well as “habitual” or “rigid” memories. The latter are frequently invoked in our daily lives and are reflexive in nature—for instance, if you take a right turn at a stop sign you pass on your way to work everyday, and you then habitually take a right instead of a left even when you are not going to work.

Previous research has shown that these different types of memories depend on different brain systems, with the hippocampus important for episodic memories and the striatum mediating habitual memories. Less understood, however, are the neurological processes by which these different kinds of memories can function as guides of attention to novel situations.

Consoling Voles Hint at Animal Empathy

Consoling Voles Hint at Animal Empathy | Social Neuroscience Advances | Scoop.it
Larry Young from Emory University, who studies prairie voles, has seen this behavior again and again. To him, it's a sign that the rodents are showing empathy.

Such claims have proven controversial in the past. For example, in 2012, scientists at the University of Chicago showed that rats will free trapped cage-mates, even if they have to sacrifice a bit of chocolate to do so. The researchers billed these rescues as evidence of empathy—that “rats free their cagemate in order to end distress.”

I Wonder What It’s Like To Have Empathy

I Wonder What It’s Like To Have Empathy | Social Neuroscience Advances | Scoop.it

There is a bit of a coldness to many of us on the spectrum. That’s not to say we’re mean. Not at all. In my experience individuals with autism tend to be more patient, loyal, and tolerant of differences than other people. But we do tend to look at things in a more utilitarian light.


Empathy means you feel what other people feel, right? That’s affective empathy. Cognitive empathy is knowing why someone feels the way they do. I read a study somewhere that said autistics have affective empathy and not cognitive. But, personally speaking, most autistics I know are much better at predicting someone’s feelings than connecting with them.


We can learn social skills with time.
