Drugs that improve brain metabolism could help Alzheimer’s patients

Posted by in categories: biotech/medical, neuroscience

Among the many ways neuroscientists think Alzheimer’s disease may strip away brain function is by disrupting the glucose metabolism needed to fuel the healthy brain. In essence, declining metabolism robs the brain of energy, impairing thinking and memory.

Against that backdrop, a team of neuroscientists at the Knight Initiative for Brain Resilience at Stanford’s Wu Tsai Neurosciences Institute have zeroed in on a critical regulator of brain metabolism known as the kynurenine pathway. They hypothesize that that the kynurenine pathway is over-activated as a result of amyloid plaque and tau proteins that accumulate in the brains of patients with Alzheimer’s disease.

Now, with support from research and training grants from the Knight Initiative, they have shown that by blocking the kynurenine pathway in lab mice with Alzheimer’s Disease, they can improve, or even restore, cognitive function by reinstating healthy brain metabolism.

How Much Longer Until Humanity Becomes A Hive Mind?

Posted by in categories: futurism, neuroscience

Last month, researchers created an electronic link between the brains of two rats separated by thousands of miles. This was just another reminder that technology will one day make us telepaths. But how far will this transformation go? And how long will it take before humans evolve into a fully-fledged hive mind? We spoke to the experts to find out.

I spoke to three different experts, all of whom have given this subject considerable thought: Kevin Warwick, a British scientist and professor of cybernetics at the University of Reading; Ramez Naam, an American futurist and author of NEXUS (a scifi novel addressing this topic); and Anders Sandberg, a Swedish neuroscientist from the Future of Humanity Institute at the University of Oxford.

Elevating Humanity Through Technology | Deep Interview with Mikey Siegel

Posted by in categories: biotech/medical, finance, robotics/AI, singularity

Mikey Siegel, with a background in robotics from the MIT Media Lab, shares insights from his decade-long exploration into technology’s role in human well-being and consciousness. He discusses the profound potential of Artificial General Intelligence (AGI) shaped with compassionate and wise values. Siegel emphasizes the importance of the human developmental process in creating benevolent AI and the integration of contemplative practices in tech development. He envisions a future where AGI supports human development globally with love and care, akin to a parent nurturing a child, ultimately fostering a connected and compassionate society.

The dangers of artificial intelligence have long loomed in our future, and seem ever closer. But it may be that the dangers of the future can reach back into the past itself, and even without a time machine.

Frontiers: Brain organoids have become increasingly used systems allowing 3D-modeling of human brain development, evolution, and disease

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

To be able to make full use of these modeling systems, researchers have developed a growing toolkit of genetic modification techniques. These techniques can be applied to mature brain organoids or to the preceding embryoid bodies (EBs) and founding cells. This review will describe techniques used for transient and stable genetic modification of brain organoids and discuss their current use and respective advantages and disadvantages. Transient approaches include adeno-associated virus (AAV) and electroporation-based techniques, whereas stable genetic modification approaches make use of lentivirus (including viral stamping), transposon and CRISPR/Cas9 systems. Finally, an outlook as to likely future developments and applications regarding genetic modifications of brain organoids will be presented.

The development of brain organoids (Kadoshima et al., 2013; Lancaster et al., 2013) has opened up new ways to study brain development and evolution as well as neurodevelopmental disorders. Brain organoids are multicellular 3D structures that mimic certain aspects of the cytoarchitecture and cell-type composition of certain brain regions over a particular developmental time window (Heide et al., 2018). These structures are generated by differentiation of induced pluripotent stem cells (iPSCs) or embryonic stem cells (ESCs) into embryoid bodies followed by, or combined, with neural induction (Kadoshima et al., 2013; Lancaster et al., 2013). In principle, two different classes of brain organoid protocols can be distinguished, namely: (i) the self-patterning protocols which produce whole-brain organoids; and (ii) the pre-patterning protocols which produce brain region-specific organoids (Heide et al., 2018).

Humans with Intelligence Amplification IA and Artificial Intelligence AI

Posted by in categories: mobile phones, robotics/AI

Everybody is talking about Artificial Intelligence (AI). It is in our computers, services and even our mobile phones. The AI composes our messages, predicts our moves and even takes photos for us. Are we – humans – going to become “obsolete” in a matter of years?! Maybe there is a last chance – Intelligence Amplification (IA).

While an AI needs to be developed from scratch, we humans, already have great intelligence thanks to countless years of evolution. A modern human’s brain is an awesome tool!

Among us, there are some geniuses, but imagine if everybody can become one. And not just a genius, but a super-genius. Smarter than every person who has ever lived before! This is the idea behind Intelligence Amplification. To use our intelligence as a base and to add computers to make us smarter beyond our imagination. A hybrid, a work of art!

Brain prosthesis passes live tissue test

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience

The world’s first brain prosthesis has passed the first stages of live testing.

The microchip, designed to model a part of the brain called the hippocampus, has been used successfully to replace a neural circuit in slices of rat brain tissue kept alive in a dish. The prosthesis will soon be ready for testing in animals.

The device could ultimately be used to replace damaged brain tissue which may have been destroyed in an accident, during a stroke, or by neurodegenerative conditions such as Alzheimer’s disease. It is the first attempt to replace central brain regions dealing with cognitive functions such as learning or speech.
