Sleep banking is essentially extending your normal sleep hours in the nights leading up to a known period of sleep deprivation. On the face of it, it appears unlikely banking sleep could counter the decreased alertness and other cognitive decrements that we experience when deprived of sleep, or stop that strong sensation we get when our body wants sleep.
Our results are highly promising, especially since currently there are no approved treatments that address the underlying cause of Dravet syndrome. Since this gene regulation product targets the actual root cause of Dravet syndrome, we observed improvements in other developmental and cognitive symptoms, in addition to seizure control. This is unprecedented.
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.
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).
Flying combat missions on little to no rest meant slower reaction times, clouded judgment, and mistakes that could cost lives. The military needed a solution, and they needed it fast. What they developed was a technique so effective that it reportedly worked for 96% of pilots after just six weeks of practice. No pills, no special equipment, just a systematic approach to shutting down your racing mind and tense body in 120 seconds or less.
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).
According to University of Michigan neuroscientists, not only can their AI vision language model diagnose neurological disorders from MRI scans with high performance accuracy, but it also has foundation model capabilities, making it a flexible, general-purpose solution that can be tailored for a wide variety of medical imaging. "These results demonstrate that Prima has foundation model properties, and reported performance will continue to improve with additional health system training data and larger compute budgets," wrote the study's authors in the preprint.
Rumination activates the default mode network (DMN) - the brain's self-referential processing system. This is the neural circuitry that fires when you're thinking about yourself in relation to others: your identity, your social standing, your mistakes. It's the brain asking, over and over, What does this say about me?
They then used emerging mathematical methods to isolate signals originating from nine brain regions previously implicated in mediating consciousness and examined connections between pairs of these regions. Among them were the parietal cortex, which is at the top of the brain about halfway between the forehead and the back of the skull; the occipital cortex, at the back of the head; and several small, deeper structures, such as one called the thalamus.
Think of your creativity like a high-performance garden: If you focus only on the visible harvest (outputs) and never allow the soil to lie fallow (liminal space) or the bees to roam freely (play), the ground eventually becomes depleted. Boredom is the signal that the soil needs replenishing, ensuring that your next season of work is a flourish rather than a struggle.
When Dr. Homoud Aldahash started the three-hour process of removing a tumor about the size of a walnut from a patient's brain, it was an experience unlike any other in his 25 years as a neurosurgeon. It wasn't Aldahash's gloved hands slicing 68-year-old Mohammed Almutrafi's right frontal lobe, but surgical instruments attached to a set of robotic arms, which Aldahash controlled from a console where he sat three meters away.
Most people will forget a name, misplace their phone, or lose track of a conversation at some point. Usually, those moments pass without much thought. But for many adults, especially as they age, small lapses can trigger a much deeper fear: Is this the beginning of cognitive decline? As a neurologist, I hear this concern often. And as a researcher, I have learned something important: Worry about cognition and cognitive disease are not the same thing.
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.
The team, which is being led by Jülich neurophysics professor Markus Diesmann, will leverage the Joint Undertaking Pioneer for Innovative and Transformative Exascale Research (JUPITER) supercomputer for their simulation. JUPITER is currently the fourth most powerful supercomputer in the world according to the TOP500 list, and features thousands of graphical processing units. The team demonstrated last month that a " spiking neural network " could be scaled up and run on JUPITER, effectively matching the cerebral cortex's 20 billion neurons and 100 trillion connections.
Before treatment began, participants underwent neuroimaging. Instead of relying on a single modality, the researchers fused structural connectivity (how regions are physically wired) with functional connectivity (how regions co-activate at rest). The goal was not to throw every possible feature at a black box, but to learn a constrained pattern-what the authors call structure-function "covariation"-that carries the most predictive signal for outcome. In other words, the model tries to find the smallest set of connections that meaningfully forecasts symptom change.
Summer passed Valerie Zeko by when she was 27, as she vegged out on the couch watching TV instead of seeing friends or exploring the overcast beach near her house. She later learned that period was her first episode of depression. I felt like the fog was in my head as well as outside, said Zeko, now 57, describing the mood disorder that would squelch her happiness, motivation and self-esteem for 28 years until she finally found effective treatment.
When a person suffers a stroke, physicians must restore blood flow to the brain as quickly as possible to save their life. But, ironically, that life-saving rush of blood can also trigger a second wave of damage - killing brain cells, fueling inflammation and increasing the odds of long-term disability. Now, in a study published in the journal Neurotherapeutics, Northwestern University scientists have developed an injectable regenerative nanomaterial that helps protect the brain during this vulnerable window.
