A characteristic of depression is a lack of motivation. Cold Spring Harbor Laboratory (CSHL) Professor Bo Li, in collaboration with CSHL Adjunct Professor Z. Josh Huang, discovered a group of neurons in the mouse brain that influences the animal’s motivation to perform tasks for rewards.

We finally know why the brain uses so much energy

Posted by in categories: biotech/medical, neuroscience

The brain is considered a very expensive organ to run.


Your brain may be leaking … energy, according to a new study that may explain why your noggin consumes 20% of the energy needed to keep your body running.

The study researchers found that tiny sacs called vesicles that hold messages being transmitted between brain cells may be constantly oozing energy, and that leakage is likely a trade-off for the brain being ready to fire at all times, according to a new study published Dec. 3 in the journal Science Advances.

Self-Administered Cognition Test Predicts Early Signs of Dementia Sooner

Posted by in categories: biotech/medical, life extension, neuroscience

Summary: A newly developed self-assessment test of cognitive function can help detect early signs of dementia sooner than commonly used office-based cognitive tests.

Many people experience forgetfulness as they age, but it’s often difficult to tell if these memory issues are a normal part of aging or a sign of something more serious. A new study finds that a simple, self-administered test developed by researchers at The Ohio State University Wexner Medical Center, College of Medicine and College of Public Health can identify the early, subtle signs of dementia sooner than the most commonly used office-based standard cognitive test.

Consciousness & Time | Part III of Consciousness: Evolution of the Mind (2021) Documentary

Posted by in categories: computing, education, information science, neuroscience, quantum physics, singularity

Most physicists and philosophers now agree that time is emergent while Digital Presentism denotes: Time emerges from complex qualia computing at the level of observer experiential reality. Time emerges from experiential data, it’s an epiphenomenon of consciousness. From moment to moment, you are co-writing your own story, co-producing your own “participatory reality” — your stream of consciousness is not subject to some kind of deterministic “script.” You are entitled to degrees of freedom. If we are to create high fidelity first-person simulated realities that also may be part of intersubjectivity-based Metaverse, then D-Theory of Time gives us a clear-cut guiding principle for doing just that.

Blood from marathoner mice boosts brain function in their couch-potato counterparts

Posted by in categories: biotech/medical, health, neuroscience

Physical exercise is great for a mouse’s brain, and for yours. Numerous studies conducted in mice, humans and laboratory glassware have made this clear. Now, a new study shows it’s possible to transfer the brain benefits enjoyed by marathon-running mice to their couch-potato peers.

Stanford School of Medicine researchers have shown that blood from young adult mice that are getting lots of exercise benefits the brains of same-aged, sedentary mice. A single protein in the blood of exercising mice seems largely responsible for that benefit.

The discovery could open the door to treatments that—by taming inflammation in people who don’t get much exercise—lower their risk of neurodegenerative disease or slow its progression.

New Imaging Method Visualizes Blood Flow in the Brain Down to a Single Blood Cell

Posted by in categories: bioengineering, biotech/medical, genetics, neuroscience

Researchers from the Skolkovo Institute of Science and Technology and Saratov State University have come up with an inexpensive method for visualizing blood flow in the brain. The new technique is so precise it discerns the motions of individual red blood cells — all without the use of toxic dyeing agents or expensive genetic engineering. The study was published in The European Physical Journal Plus.

To understand more about how the brain’s blood supply works, researchers map its blood vessel networks. The resulting visualizations can rely on a variety of methods. One highly precise technique involves injecting fluorescent dyes into the blood flow and detecting the infrared light they emit. The problem with dyes is they are toxic and also may distort mapping results by affecting the vessels. Alternatively, researchers employ genetically modified animals, whose interior lining of blood vessels is engineered to give off light with no foreign substances involved. Both methods are very expensive, though.

Researchers from Skoltech and Saratov State University have devised an inexpensive method for visualizing even the smallest capillaries in the brain. The method — which integrates optical microscopy and image processing — is dye-free and very fine-grained, owing to its ability to detect each and every red blood cell travelling along a blood vessel. Since the number of RBCs in capillaries is not that high, every cell counts, so this is an important advantage over other methods, including dye-free ones.
