SFU researchers, led by professor Ryan D’Arcy with partners from the
Mayo Clinic, Sheba Medical Centre in Israel and local high-tech company
HealthTech Connex Inc., are developing a more accessible means to
monitor brain health.
In a recent article published in the journalFrontiers in Neuroscience,
the team introduces the world’s first advancement in physiology-based
brain vital signs. Their discovery makes it possible to translate
complex brainwaves into objective, practical and deployable brain vital
signs, using longstanding brainwave technologies that have existed for
nearly a century.
HealthTech Connex Inc. is currently developing the NeuroCatchTM platform to enable the highest quality recordings of the brain’s vital signs.
“The brain vital-sign framework described in Frontiers in Neuroscience
represents the first step towards an easy way to monitor brain health,”
says D’Arcy. “Potential applications are in concussion, brain injury,
stroke, dementia and other devastating brain diseases and disorders.”
Vital sign measures are often used in clinics, hospitals and other
care centres to assess the performance of various body systems.
Scientists in D’Arcy’s NeuroTech Lab, based in Surrey Memorial
Hospital, have now developed a simple way to measure brain health over
time by using non-invasive electrodes to track the brain’s electrical
activity for key brain functions—in other words, the brain’s vital
Researchers found that it is possible to monitor brain performance
during auditory sensation, and basic attention and cognitive processing.
“We know brainwaves provide an objective physiological measurement of
brain functions,” says D'Arcy, SFU’s BC Leadership Chair in Medical
Technologies. “We’ve been working for the last 20 years to solve the
major gap in terms of utilizing this for a rapid and accessible vital
sign for brain function.”
Traditionally, brain function has been assessed only after trauma or
disease has occurred and has relied heavily on subjective,
“However, tracking our brain’s vital signs is critically important
for establishing a baseline for a person’s objective brain activity,” he
adds, noting that in the event of injury or disease, it then becomes
possible to evaluate if brain function changes, and whether treatments
“We describe the world’s first physiology-driven brain vital-sign
measure allowing us to quantify brain vitality over time,” says Sujoy
Ghosh Hajra, a PhD student working with D’Arcy and the paper’s lead
In the paper, researchers describe how their framework translates
complex brainwave science into clinically accessible information and
demonstrates successful measurement of brain vital signs in both younger
and older adults. Their method identified age-related brain function
changes that were not evident using traditional measures.
The paper has had significant hits—more than 1,000 views
globally—which Ghosh Hajra says is a testament to the urgent need to
quantify brain vitality.
A group of Haida elders in their nineties gathered around a microphone on Lucy Bell’s dining room table. Every Haida word they spoke into it was another word recorded for future generations.
It was a touching experience for Bell. Her grandmother spoke Haida, a language also known as Xaad Kil and X̱aaydaa Kil when she was young.
“Many in my generation grew up hearing it but not speaking it, and knowing how precious it was to learn it,” said Bell, now 45 and co-ordinator at Haida Gwaii’s Xaad Kihlga Hl Suu.u Society of language. She learned Haida as an adult.
Indigenous languages in Canada are declining as elder native speakers die. Not long after Bell made the Haida recordings, two of the elders who participated passed away.
The language project that Bell is a part of began in 2013. The Social Sciences and Humanities Research Council (SSHRC) of Canada awarded a $2.5-million partnership grant to Simon Fraser University’s First Nations Language Centre. The money supports a seven-year project to preserve and revitalize the languages of 22 First Nations groups in British Columbia and Yukon, with technology playing a large role.
The language recordings that Bell and others produced are more than simple records; they’re part of interactive lessons for web and mobile apps. Bell’s dream is that the new tools will help teach Indigenous youth their languages as early as possible.
“We’re at a watershed moment,” said Marianne Ignace, director of the First Nations Language Centre. “Many languages only have a handful or even fewer elderly people who were raised speaking those Indigenous languages in the home, and once that generation is gone, that’s kind of it.”
There’s also the history of residential schools that “literally beat the language out of First Nations children,” Ignace said.
hello can we go back to season 2 at least we had yearbook semi formal and creativity maybe the opening credits were dumb but at least people werent accusing people of beCOMING other people and being in love with someone to mAKE SURE THEYRE RIGHT FOR SOMEONE I MEAN WHO IN THEIR RIGHT FUCKING MINDNDNDN
i though any other anon still got any doubt about KS situation in secret night might want to watch this youtu*be/-xxvNvojg8I . Someone mention in 1:39 he cracked(exactly at the time JI ruffle his hair). But he did 'look like' he is holding something-
The atmosphere kinda tense between those two in SFU. But Idk what time fmaster actually take the pic of KS with teary eyes. Just want to help the lost soul.
(x) Thank you for the video, hopefully this clarifies things better.
