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."

"Beyond the Brain" In the 1990s, scientists declared that schizophrenia and other psychiatric illnesses were pure brain disorders that would eventually yield to drugs. Now they are recognizing that social factors are among the causes, and must be part of the cure.

"...Pam agreed to die in order to save her life—and in the process had what is perhaps the most famous case of independent corroboration of out of body experience (OBE) perceptions on record...Pam later said, she felt herself “pop” out of her body and hover above it, watching as doctors worked on her body. Although she no longer had use of her eyes and ears, she described her observations in terms of her senses and perceptions...with considerable accuracy.
NDE studies [such as these] suggest that after physical death, mind and consciousness may continue in a transcendent level of reality that normally is not accessible to our senses and awareness."

"Piloting London’s distinctive black cabs (taxis to everyone else) is no easy feat. To earn the privilege, drivers have to pass an intense intellectual ordeal, known charmingly as
The Knowledge. Ever since 1865, they’ve had to memorise the location of every street within six miles of Charing Cross – all 25,000 of the capital’s arteries, veins and capillaries. They also need to know the locations of 20,000 landmarks – museums, police stations, theatres, clubs, and more – and 320 routes that connect everything up." Acquiring
The Knowledge changes the brains of those who acquire it.

The International Science & Engineering Visualization Challenge 2010 - "Researchers are generating mind-boggling volumes of data at exponentially increasing rates. The ability to process that information and display it in ways that enhance understanding is an increasingly important aspect of the way scientists communicate with each other and—especially—with students and the general public. That's why, for the past 8 years, Science and the U.S. National Science Foundation (NSF) have co-sponsored annual challenges to promote cutting-edge efforts to visualize scientific data, principles, and ideas.
This year's awardees span scales from nanoparticles to colliding galaxies, and from microseconds to millennia."

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "
soul dust": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter,
it is also undermined by it. It all depends how you think it.

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

Neurosecurity: security and privacy for neural devices. "An increasing number of neural implantable devices will become available in the near future due to advances in neural engineering. This discipline holds the potential to improve many patients' lives dramatically by offering improved—and in some cases entirely new—forms of rehabilitation for conditions ranging from missing limbs to degenerative cognitive diseases. The use of standard engineering practices, medical trials, and neuroethical evaluations during the design process can create systems that are safe and that follow ethical guidelines; unfortunately, none of these disciplines currently ensure that neural devices are robust against adversarial entities trying to exploit these devices to alter, block, or eavesdrop on neural signals. The authors define 'neurosecurity'—a version of computer science security principles and methods applied to neural engineering—and discuss why neurosecurity should be a critical consideration in the design of future neural devices."

We've discussed
trepanation, the boring of holes in the head as practiced in antiquity and by a fringe do it yourself-ers, before. There now seems to be research indicating that the procedure may have
medical merit, and even help stave off age related cognitive decline. This curious research brought to you by the
Beckly Foundation which "promotes the investigation of consciousness and its modulation
from a multidisciplinary perspective" and has a sweet logo.
