Play is hard to tamp down, and exuberance breaks through even as busy spacefarers are carrying along the weighty hopes of humanity.

"For the ones who are confined in certain spaces or cannot do it independently, this is a great opportunity to transport them to a different reality from the ones that they are currently living in while keeping them active," Munoz told CBC Hamilton from his lab on Laurier's Brantford campus.

By directly recording brain activity, our study shows, for the first time in humans, that even a single bout of exercise can rapidly alter the neural rhythms and brain networks involved in memory and cognitive function.

If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.

Artificial intelligence (AI) machine learning is making a difference in assistive technology to help restore movement for the paralyzed. A new study in the American Institute of Physics journal APL Bioengineering shows how AI has the potential to restore lower-limb functions in those with severe spinal cord injuries (SCIs) by identifying patterns in brain signals captured noninvasively via electroencephalography (EEG).

Do you blame others for the choices you are making? Have you blamed others for the previous choices you have made? To shed more light on these questions, you might also ask yourself: "What am I responsible for, and what power do I have?" From there, you might agree with this self-reflective response: "I am responsible for, and I've got the power over what I think, do, say, learn, and choose" (Purje, 2014).

When you have an acute injury, your body is sending signals through the peripheral and central nervous systems and the immune system to say, hold on, I need to stop doing this so we can allow the tissue to heal, says Ericka Merriwether, a physical therapist and pain researcher at New York University. Rest, after all, is the first part of the familiar RICE therapy, which stands for rest, ice, compression and elevation.

If you're going to prioritize one thing for your brain health, make it this: regular aerobic exercise. Multiple large-scale studies show that aerobic exercise doesn't just keep your heart healthy-it directly impacts your brain structure. One year of aerobic exercise in older adults led to significantly larger hippocampal volumes and better spatial memory. Other trials documented that exercise actually slows age-related gray matter volume loss.

It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity, and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles.

In a recent article for Vogue, California-based physician Dr. Chris Renna said: "Stronger leg muscles are linked to better cognitive function in aging mainly through their effects on blood flow, metabolic health, brain structure, and physical/social activity patterns." Muscle mass starts to decline at age 30. As the largest muscle group in the body, maintaining muscle strength in the thighs and glutes is especially important for healthy aging-and apparently, brain function.

Betley and his colleagues were curious about what happens in the brain as people get stronger through exercise. They decided to focus on the ventromedial hypothalamus, a brain region that regulates appetite and blood sugar. The team then zeroed in on a group of neurons in that region that produce a protein called steroidogenic factor 1 (SF1), which is known to play a part in regulating metabolism. A previous study found that the deletion of the gene that codes for SF1 impairs endurance in mice.

Scroll through any wellness feed, and you might notice the same whiplash-inducing pattern. Dissociation is either a dangerous sign of pathology or "a protective intelligence that deserves reverence." Trauma responses are framed as evidence of brokenness or badges of resilience. Anxiety is either a disorder to eliminate or an intuition to honor. We've flattened the rich, complex reality of the nervous system into a binary: demonize or romanticize. But neither extreme helps us understand ourselves-or decide when we actually need support.

In 2018, Sharples and his research lab, now at the Norwegian School of Sport Sciences in Oslo, were the first to show that exercise could change how our muscle-building genes work over the long term. The genes themselves don't change, but repeated periods of exertion turns certain genes on, spurring cells to build muscle mass more quickly than before. These epigenetic changes have a lasting effect: Your muscles remember these periods of strength and respond favorably in the future.
