Just as engineers are able to reroute a river around a rockslide, medical professionals might have the capability to guide a brain affected by a stroke to utilize intact neural pathways, significantly enhancing the chances of a more thorough and effective recovery.
However, before they can achieve this, researchers need to determine the nature of the signals that prompt the brain to opt for more efficient neural circuits. Key questions remain: What triggers these signals? Can they be harnessed to enhance therapeutic outcomes for individuals with brain damage?
Faculty members from the UNC School of Medicine, Adam Hantman, Ian Shih, and their colleague John W. Krakauer from the prestigious Johns Hopkins University, are embarking on this critical research initiative, backed by a substantial $1.3 million grant from the renowned W.M. Keck Foundation, which has championed groundbreaking medical and scientific research for the past 70 years.
The grant is vital for Hantman and his team, offering them essential resources to delve deeply into this innovative concept, despite starting from foundational premises in their studies.

Basic science and seeking answers
Revisiting the analogy of the obstructed river, it becomes evident that engineers need to gather vital information to devise a new, accessible channel that effectively restores the river’s flow. But how do these professionals identify the obstacles lurking beneath the surface?
Krakauer, a principal investigator and respected authority in stroke rehabilitation, emphasizes that while significant research has been executed in this domain, they have yet to uncover definitive solutions.
With advanced tools at their disposal and an innovative approach to questioning, Krakauer stated, “this is a prime opportunity to probe a plethora of seemingly simple yet fundamental inquiries, providing a fresh perspective on previously explored concepts.”
The research team aims to establish sophisticated mechanisms and robust study protocols to investigate the fundamental elements—the “whats,” the “hows,” the “wheres,” and the “whys”—behind the brain’s adaptability in switching to healthier circuitry. They maintain hope that these insights will significantly translate into applications for human rehabilitation post-stroke, as there may be shared responses despite variations in damage type.
As Krakauer elaborated, “the aspiration is that the foundational science we uncover will guide us to actionable strategies for enhancing the quality of recovery for those affected.”

Cautious optimism for pioneering applications
Despite being in its infancy, the project spearheaded by Hantman, Shih and Krakauer shows promise for revolutionizing stroke recovery methodologies by elucidating the intricate mechanisms that govern brain function.
Dr. David Hwang, a respected professor in the neurology department at the UNC School of Medicine who is not directly involved with the research, echoes this sentiment. He highlights that there remains a significant gap in knowledge concerning the processes of brain recovery following a stroke, which hampers the development of effective intervention strategies.
“Insights gleaned from this venture could pave the way for innovative therapeutic approaches aimed at enhancing recovery outcomes,” he remarked.
He further noted the intriguing observation that higher levels of impairment are often associated with better recovery results. “One could envision future therapies where specific, post-stroke-affected regions of a patient’s brain are intentionally deactivated using noninvasive techniques, thereby enabling the recruitment of healthier brain areas to boost overall neurological function.”
With an innovative approach and backing from the W. M. Keck Foundation’s pivotal grant, the research team aspires to create substantial advancements in understanding the fundamental neural communications occurring within the brain, striving to unlock new avenues for enhanced stroke recovery strategies.
Like Redirecting a River – The Ingenious Work of Clinicians in Stroke Recovery
Ah, engineers, those wizards of the concrete world! They can redirect a river like it’s a stubborn toddler refusing to wash their hands. And now, it seems our clinicians have taken a page out of their playbook, attempting to help brains damaged by strokes switch back to their healthier counterparts. Imagine the brain as a dodgy internet connection—somewhere out there is the golden signal that gets everything back online. So, where’s the Wi-Fi router for that?
Scientists on a Quest: The Pioneers of Brain Recovery
Meet the dynamic trio of the brain recovery universe: Adam Hantman, Ian Shih, and John W. Krakauer, a stroke recovery guru from Johns Hopkins. With a juicy $1.3 million grant from the notorious W.M. Keck Foundation—which has been funding groundbreaking research longer than most of us have known how to tie our shoelaces—they’re setting out to explore brain signals like they’re on a treasure hunt in a corn maze!
“This grant is our runway,” Hantman noted, “and let’s be honest, we’re still at the start of our journey.” It’s a bit like having a starter pack at a game where the first level is easier than finding your socks in the morning!
Hantman’s team uses a nifty noninvasive technique on mice called optogenetics, temporarily shutting down parts of the cerebral cortex with a beam of light. Because who needs lasers for cats, right?
Basic Science: Where Questions Are Born (and Sometimes Drown)
Just as engineers decipher how to build a detour around a rockslide, Krakauer and his crew face the conundrum of identifying the brain’s blockage. It’s like asking, “Where did all the missing socks go?”—we know they’re somewhere, just not on our feet!
A wealth of research on stroke recovery exists, but it’s as though all the books fell off the shelf, and now they’re putting the pieces back together. “With new tools, we get to revisit basic yet fundamental questions in a ‘2.0’ version,” Krakauer declared. It’s like upgrading from dial-up to fiber-optic—who knew we could move this quickly?
The challenge lies in deciphering how the brain pivots to utilize undamaged circuitry—a bit like playing Twister with a group of bemused people. The goal? Enhancing recovery prospects for strokes. Krakauer optimistically muses that this basic science could illuminate glimmers of hope for real-world applications. And let’s face it, who doesn’t love a good comeback story?
Meet Song and Albert, who are busy creating devices that could take a peek into mouse brains. Good luck explaining that to your friends!
A Spark of Hope in Stroke Recovery
The scholars admit they’re still in the early stages, but there’s cautious optimism brewing like a strong cup of coffee that could power a black hole. The essence of their work may shed light on stroke recovery, examining the underlying mechanisms of the brain.
One approving voice is Dr. David Hwang, who agrees that there’s a staggering amount we don’t yet comprehend about how brain function recovers post-stroke. It’s like trying to build IKEA furniture with instructions in a foreign language; incredibly challenging and often confusing!
Dr. Hwang brilliantly highlights the paradox where higher impairments can lead to better recovery outcomes. “Imagine a future where we deactivate specific brain areas affected by strokes as a therapy—encouraging healthy areas to snap into action like they’re suddenly winning at Monopoly,” he muses. Now that’s a board game I’d like to see!
With their efforts and the unwavering support from the W.M. Keck Foundation, Hantman, Shih, and Krakauer seek to break through the thick fog of stroke recovery science. Expect more twists, turns, and possibly even a few chuckles in the brave new world of brain recovery!
