Nanowire Mesh Monitors Mouse Brains - "Injectable 'neural lace'* brain-computer interface works in mice for months at a time." (via) [more inside]
Maia Szalavitz [mefi's own maias] talks about her new book, Unbroken Brain: A Revolutionary New Way of Understanding Addiction on Fresh Air with Terry Gross (transcript) - "We have this idea that if we are just cruel enough and mean enough and tough enough to people with addiction, that they will suddenly wake up and stop, and that is not the case."
Magic Mushroom Drug Lifts Depression in Human Trial - "The findings show that more research in this field is now needed. 'This is the first time that psilocybin has been investigated as a potential treatment for major depression', says lead author Dr Robin Carhart-Harris, Imperial College London."
Lo and Behold: Reveries of the Connected World - "With interviewees ranging from Elon Musk to a gaming addict, Werner Herzog presents the web in all its wildness and utopian potential in this dizzying documentary." (via)
The Deep Mind of Demis Hassabis - "The big thing is what we call transfer learning. You've mastered one domain of things, how do you abstract that into something that's almost like a library of knowledge that you can now usefully apply in a new domain? That's the key to general knowledge. At the moment, we are good at processing perceptual information and then picking an action based on that. But when it goes to the next level, the concept level, nobody has been able to do that." (previously: 1,2) [more inside]
Locked-In Man - "Martin Pistorius spent more than a decade unable to move or communicate, fearing he would be alone, trapped, forever. NPR's new show Invisibilia tells how his mind helped him create a new life."
How Tripping On Mushrooms Changes The Brain - "New research [pdf] suggests that psilocybin, the main psychoactive ingredient in magic mushrooms, sprouts new links across previously disconnected brain regions, temporarily altering the brain's entire organizational framework." [more inside]
Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]
The simulated brain - "First computer model to produce complex behaviour performs almost as well as humans at simple number tasks." [1,2,3,4,5,etc.]
Chimp Fights and Trolley Rides from Radiolab's morality episode: "try to answer tough moral quandaries. The questions--which force you to decide between homicidal scenarios--are the same ones being asked by Dr. Joshua Greene. He'll tell us about using modern brain scanning techniques to take snapshots of the brain as it struggles to resolve these moral conflicts. And he'll describe what he sees in these images: quite literally, a battle taking place in the brain. It's 'inner chimp' versus a calculator-wielding rationale."
The Root of Knowledge - "Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at 'Philosophy.' " (via) [more inside]
The simulated brain - "The scientists behind Blue Brain hope to have a virtual human brain functioning in ten years... Dr. Markram began by collecting detailed information about the rat's NCC, down to the level of genes, proteins, molecules and the electrical signals that connect one neuron to another. These complex relationships were then turned into millions of equations, written in software. He then recorded real-world data -- the strength and path of each electrical signal -- directly from rat brains to test the accuracy of the software." Is it possible to digitally simulate a brain accurately? Can it only be analog? And are there quantum effects to be considered? (previously 1 2 3 4) [more inside]
