“Our results essentially showed the children who grew up in disadvantaged neighborhoods had brains that looked older than was typical for their age during early adolescence… What’s more, these associations held true even when we accounted for household socioeconomic status and other adversities (such as childhood abuse and neglect), which suggests that neighborhood disadvantage has a unique role to play in brain development.

MDMA-assisted therapy for PTSD edges closer

Phase 3 clinical trials of MDMA-assisted psychotherapy for post-traumatic stress disorder (PTSD) are currently underway in the USA, Canada, and Israel.

These trials, led by the Multidisciplinary Association for Psychedelic Studies (MAPS), are the last step in figuring out if this treatment is safe and effective enough for MDMA to be legally prescribed to treat PTSD.

If there’s a positive result from the trials, this could happen in the USA as soon as 2022.

Algorithms mimic the process of biological evolution to learn efficiently

Uncovering the mechanisms of learning via synaptic plasticity is a critical step towards understanding how our brains function and building truly intelligent, adaptive machines. Researchers from the University of Bern propose a new approach in which algorithms mimic biological evolution and learn efficiently through creative evolution.

Our brains are incredibly adaptive. Every day, we form new memories, acquire new knowledge, or refine existing skills. This stands in marked contrast to our current computers, which typically only perform pre-programmed actions. At the core of our adaptability lies synaptic plasticity. Synapses are the connection points between neurons, which can change in different ways depending on how they are used. This synaptic plasticity is an important research topic in neuroscience, as it is central to learning processes and memory. To better understand these brain processes and build adaptive machines, researchers in the fields of neuroscience and artificial intelligence (AI) are creating models for the mechanisms underlying these processes. Such models for learning and plasticity help to understand biological information processing and should also enable machines to learn faster.

Neuromorphic electronics based on copying and pasting the brain

This Perspective explores the potential of an approach to neuromorphic electronics in which the functional synaptic connectivity map of a mammalian neuronal network is copied using a silicon neuro-electronic interface and then pasted onto a high-density three-dimensional network of solid-state memories.

Strategies for the Regeneration of Myelin

The degradation and regeneration of myelin sheaths characterize neurological disorders such as multiple sclerosis. Cholesterol is an indispensable component of myelin sheaths. The cholesterol for the regenerated myelin sheaths must therefore either be recycled from damaged myelin or produced again locally.

In a recent study, scientists at the Max Planck Institute for Experimental Medicine in Göttingen, led by Gesine Saher, found that in the case of chronic damage, unlike in acute damage, hardly any cholesterol is recycled. Instead, the new production of cholesterol determines the efficiency of the repair. Unexpectedly, not only the myelin-forming cells themselves but also nerve cells make an important contribution to regeneration.

Cholesterol synthesis in nerve cells ensures the replenishment of newly myelin-forming cells. This could impact the therapeutic success for myelin disorders such as multiple sclerosis.

Becoming Immortal for 10,000$? — Upload Your Mind THIS DECADE!

Becoming Immortal through Mind Uploading sounds like something that’ll only be possible around the 2100’s. But amazingly, a group of scientists at Nectome are working on giving us the ability to live forever inside of a computer simulation by the end of this decade for around 10000$.

Ray Kurzweil, director of engineering at Google, has long predicted that people will be able to upload their entire brains to computers and become digitally immortal by 2045. Kurzweil made this claim for many years, e.g. during his speech in 2013 at the Global Futures 2045 International Congress in New York, which claims to subscribe to a similar set of beliefs. Mind uploading has also been advocated by a number of researchers in neuroscience and artificial intelligence, such as the late Marvin Minsky.

HalfDive VR Headset Takes Design Cues from ‘Sword Art Online’ NerveGear, Coming to Kickstarter in December

Japanese startup Diver-X is looking to launch a SteamVR-compatible headset that seems to be taking a few ideas from popular anime Sword Art Online, which prominently features a fully immersive metaverse. While it’s not a brain-computer interface like the “full dive” NerveGear featured in the show, the heavy-weight hardware presents a pretty interesting approach to VR headset design.

Called HalfDive, the Tokyo-based company says its taking advantage of the sleeping position to “enabl[e] human activity in its lowest energetic state.”

Since it’s worn laying down, the creators say they’re freed from many of the design constraints that conventional VR headset makers are used to pursuing with the introduction of things like pancake optics and microdisplays. Since the weight isn’t on your neck, it doesn’t have to be light or slim.
