Dementia changes brain size and structure in similar ways in both dogs and humans. As the disease kills off neurons, the brain shrinks, and the middle cavity enlarges.

NEW - Dr. Deborah Birx Says 'Long COVID' is Similar to HIV "HIV quietly destroyed our immune system...We're learning now about mitochondria and viral impact and brain fog and the changes in our neurons and the cells that nourish our neurons that really allow us to think and move, and we're learning that because what long COVID has done."

EINSTEIN’S BRAIN AND THE NEURONS THAT TAUGHT THEMSELVES PONG When Einstein died, scientists studied his brain to see what set it apart. Most of it looked ordinary, except for one thing: the folds. His brain had far more of them than average. More folds meant more surface area, and more surface area meant more neurons. The difference was concentrated in his parietal lobes, the regions tied to math and spatial reasoning. Genius left a trace, but it was subtle, hidden in structure rather than size. Decades later, another mystery arrived. In 2022, researchers at Cortical Labs grew human neurons in a Petri dish and wired them to a chip running the game Pong. There was no human player, no brain, and no mind, just cells, signals, and feedback. Yet somehow, the neurons learned. The longer they played, the better they became. That forced an uncomfortable question: how does a group of disconnected neurons know how to play a game it has never seen. The answer is still unclear. Einstein’s brain revealed how intelligence can be built. Source: Joe Rogan

Mirror neurons are among the most mysterious cells in the brain. They activate both when you perform an action and when you watch someone else do the same thing, allowing your brain to internally simulate another person’s experience. [🎞️ thebrainmaze]

Dyno Therapeutics co-founder Sam Sinai on how his team cracked the blood-brain barrier well enough to reach 50% of neurons with a single injection: "For brain specifically, the brain has this extra layer of defense called the blood brain barrier. It's really put there to prevent anything to get in." "What we have done is actually in primates we can show that we can get up more than 50% of neurons, through a systemic injection." "You're just injecting in the veins, and then the virus actually makes its way into the brain." "Neurons are a primary target, but it could be in some cases glial cells, depending on the disease. Solving pan brain, meaning all of brain delivery, is a key objective there."

Robert Sapolsky is the Stanford neuroscientist who proved stress ages you from the inside. Cortisol shrinks your brain, killing memory neurons — and it may not reverse. Here are 7 natural ways to slow the clock (without medication): 1. Cold water on your face.

$BRAIN just got a real brain. v0.4.0 runs the full MaleCNS v1.0 connectome: 166,700 neurons and 124M synapses firing in one spiking simulation. Camera motion now reaches identified fly visual neurons, travels through the wiring, and triggers real escape and steering circuits that produce motor commands. The loop already runs up to 6.5x real time on an RTX 3050. Shuffle the connectome and the behaviour vanishes. The wiring is doing the work. Next up: transaction → sensory neurons → 166,700-neuron brain → movement

A study has found the menopause is linked to changes in the brain similar to those seen in Alzheimer's. Researchers found a significant loss of grey matter in post-menopausal women that could help explain why there are almost twice as many cases of dementia in women as in men.

Brain-wide neuron tracing reveals that the mysterious mouse claustrum is highly connected to the rest of the brain. In this extreme example, several neurons wrap their axons entirely around the cortex, forming a crown-like structure. 👑 More: #SciShots

Want to keep your brain sharp and lower your risk of dementia? In this week’s episode, Dr. Tommy Wood (Tommy Wood MD, PhD) joins the podcast for a discussion on enhancing brain health and performance. Tommy, an M.D., Ph.D., is an expert in brain health, longevity, cognitive performance, concussion, and more. In this conversation, we discuss how dementia and late-onset Alzheimer’s disease are largely preventable through specific actions. Tommy shares in this clip that the risk of dementia and late-onset Alzheimer’s is drastically reduced by the extent of early-life education and how cognitively stimulating life remains afterward. The takeaway: Cognitive stimulation is crucial. The brain needs regular challenges throughout life. Early education is valuable, as is a mentally demanding job. However, if you don’t have these, be sure to read challenging books, learn a language, join a dance class, or practice jiu-jitsu. Do whatever it takes to challenge your brain—this stimulus is critical.
