🚨 SCIENTISTS ARE USING AI TO MAP A HIDDEN “CLEANING SYSTEM” INSIDE THE HUMAN BRAIN AND IT COULD CHANGE HOW WE UNDERSTAND SLEEP, AGING, AND NEURODEGENERATIVE DISEASE. It’s called the glymphatic system a vast network of fluid channels that flushes toxic waste from the brain while you sleep. For years it was almost impossible to observe in detail. Now AI-powered imaging is revealing it like a living galaxy of microscopic rivers and pathways inside neural tissue. Why this matters: Your brain produces toxic proteins constantly. The glymphatic system is one of its primary waste-clearance mechanisms clearing the very proteins linked to Alzheimer’s, Parkinson’s, and other neurodegenerative diseases. But here’s the unsettling part: This cleaning system becomes dramatically less efficient with age, poor sleep, stress, and brain injury. Sleep may not just “rest” your mind it may literally wash your brain. The deeper implication is staggering: The brain isn’t just a computer. It’s a dynamic, living network that constantly rebuilds and cleanses itself in real time. The more we map it, the more it looks like an entire universe of connected energy flows inside our skulls. What if some neurological diseases begin when the brain can no longer properly “wash” itself at night? Follow for more frontier neuroscience and future technology.

My APM is over 700 because I wavedash with tap jump, L-Cancel with Z and constantly micro-drift in the air Mashing mindlessly on respawn or during rest sleep animation isn’t nearly enough to get a game-wide average of 10 inputs per second lol

Like a stadium full of sports fans doing the wave, neurons coordinate their electrical signals in rhythmic patterns that sweep across the cortex, the brain’s outermost layer. Recent studies in humans and animals have shown these patterns, called traveling waves, can take on complex shapes, among them a rotating spiral that has been observed during deep sleep, memory retrieval, and other brain processes. A new study has now captured the fast-spinning waves spanning whole brains, offering clues to how they’re organized and what they might do. Learn more: News from Science

MIT ROBOT THREAD PERFORMS BRAIN SURGERY WITH PRECISION Neuroscience just leveled up. MIT built a magnetic thread robot that can slip through the brain’s delicate vessels to clear deadly clots without opening the skull. No scalpels, no invasive drilling—just control, precision, and futuristic tech guiding a thread where human hands can’t go. A real step toward safer, faster brain surgery. Medicine isn’t just healing anymore, it’s engineering miracles at the smallest scale. Source: the.blacklist.bureau

In Congo, when people die, relatives clothe, unclothe, and wash the body. During an Ebola outbreak, this spreads the disese like crazy. When an Ebola treatment center wouldn't hand over a body to relatives, they burned the place down. Africans like to do things their way.

During a medical procedure in 2020, Dagmar Turner performed her violin while surgeons operated to remove a tumor from her brain's right frontal lobe. This unique act aimed to help surgeons avoid harming the brain region responsible for coordination and delicate hand movements, crucial for her musical abilities. Thankfully, the surgery was successful.

In 1964, a 17 year old from San Diego conducted the most dangerous psychology experiment ever attempted by a teenager. Randy Gardner stayed awake for 264 hours (11 days) with: • No stimulants • No caffeine • No medical suppressants And Stanford sleep researchers realized too late they couldn't stop him. What happened inside his brain during those 264 hours rewrote everything we thought we knew about consciousness. By day three, Randy's short term memory had completely collapsed. He couldn't remember starting a sentence by the time he reached the end of it. Researchers would ask him to count backward from 100, and he'd stop at 65, staring blankly, having forgotten the entire concept of numbers. But the terrifying part wasn't the memory loss. Randy's brain began creating a second reality that ran parallel to the real one. He'd have full conversations with people who weren't there. He'd walk to locations that didn't exist. His eyes stayed open, his body kept moving, but his mind was living inside elaborate hallucinations that felt completely real to him. Sleep researchers had predicted cognitive decline. They hadn't predicted that the sleep deprived brain would start *manufacturing* an alternate conscious experience to fill the gap. Dr. William Dement, the Stanford researcher monitoring Randy, discovered something that changed sleep science forever. The hallucinations weren't random. They followed the exact same patterns as REM sleep dreams, complete with narrative arcs, emotional themes, and symbolic imagery. Randy's brain was dreaming while awake, projecting dream content directly onto his waking perception. The boundary between sleep and consciousness was more than binary. It was fluid, and without sleep to maintain the separation, the two states began bleeding into each other. By day nine, Randy couldn't distinguish between his hallucinations and reality. He became convinced that Dr. Dement was plotting against him. He accused the researchers of being imposters. His paranoid delusions were so convincing that even the people documenting his mental breakdown began questioning their own perceptions. Randy's EEG readings showed something unprecedented. His brain waves were cycling through all four stages of sleep while he remained physically awake and mobile. His neurons were firing in sleep patterns, but his motor cortex kept his body upright and functioning. He had become a walking sleeper, a conscious dreamer, a person experiencing two incompatible states of being simultaneously. When Randy finally slept after 264 hours, he didn't collapse into a coma. He slept for 14 hours and 40 minutes, then woke up completely normal. The hallucinations vanished. The paranoia disappeared. His memory returned. But the Stanford team realized they had documented something extraordinary about human consciousness that nobody talks about. Your brain doesn't need sleep to *function*. Randy proved the human body can operate for weeks without it. What your brain needs sleep for is to maintain the distinction between internal mental reality and external physical reality. Sleep isn't rest for your body. Sleep is a firewall for your mind. Without that firewall, the dream world and waking world merge into a single, indistinguishable experience where hallucinations become as real as the room you're sitting in. Randy recovered completely, but sleep researchers never attempted the experiment again. The ethical implications were too severe. They had accidentally discovered that consciousness is far more fragile than anyone suspected, held together by nothing more than eight hours of unconsciousness every night. Every time you go to sleep, your brain is performing the most critical maintenance operation in human biology. It's rebuilding the wall between dreams and reality. And without that wall, there is no difference.

Did you know? Swifts eat, sleep, drink, mate, & even bathe on the wing...rarely landing except to nest. They can switch off one half of their brain to rest, drink by gliding low over water to take sips, & fly through rain to bathe! 🌧️ #SwiftAwarenessWeek 📽️ David @ The HALL of EINAR

🚨STUDY: MAGIC MUSHROOM COMPOUND "RESETS" BRAIN Psilocybin, the hallucinogenic compound in magic mushrooms, temporarily resets entire brain networks controlling time and self-perception, according to a new Nature study. Researchers observed "massive changes" in seven volunteers' brains, with some patterns resembling entirely different individuals. Most changes lasted hours, but one brain link remained disrupted for weeks. The default mode network, active during daydreaming, became desynchronized during drug effects. Interestingly, "grounding" techniques used in psychedelic therapy reduced psilocybin's brain impact. This research could explain psilocybin's potential therapeutic effects on depression and PTSD. While not proving causation, it offers crucial clues for developing mental health treatments. The study's innovative approach, repeatedly imaging fewer subjects, provided unprecedented insight into psilocybin's whole-brain impact. Researchers hope to extend this work to individuals with conditions like depression. Source: Nature , Joshua Siegel

These leftist fundamentalists are a complete enigma for me. They wants to change the world by spilling buckets of paint which she can't even spill without making a mess of herself. So after their 5 minutes of Tiktok fame is over they are going to waste 300 liters of water just to wash out the paint that she just used to show us how she is fighting for preservation of nature? Does this make any sense?
