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]
