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

Are you tired of reading about how neuroscientists have discovered the area of the brain devoted to a single, oddly-specific function, but lack access to the sophisticated neuroimaging technologies needed to refute them? NeuroSynth
has you covered. [more inside]

The Brain on Trial.
Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order.
"We may someday find that many types of bad behavior have a basic biological explanation—as has happened with schizophrenia, epilepsy, depression, and mania." [more inside]

An idle brain may be the self's workshop.
'Recent research suggests that mind-wandering may be important and that knowledge of how it works might help treat such conditions as Alzheimer's disease, autism, depression and schizophrenia.' Once upon a time, scientists didn't regard idle musings of the wandering mind as very important. 'But in the span of a few short years, they have instead come to view mental leisure as important, purposeful work — work that relies on a powerful and far-flung network of brain cells firing in unison. Neuroscientists call it the "default mode network."''Understanding that setting may do more than lend respectability to the universal practice of zoning out: It may one day help diagnose and treat psychiatric conditions as diverse as Alzheimer's
— all of which disrupt operations in the default mode network. Beyond that lies an even loftier promise. As neuroscientists study the idle brain, some believe they are exploring a central mystery in human psychology: where and how our concept of "self" is created, maintained, altered and renewed.'

Optimizing Your Brain at Work
is a pretty fascinating talk at Google by David Rock about managing your brain's internal states and attention, as well as threat responses with the goal of optimizing information processing. It is a Youtube link, and fairly long (~55min). He also mentions The Neuroscience of Mindfulness
during the talk, so here is a convenient link to that.

A gene variant associated with serotonin transport (STG) ,
and normally associated with depression is strangely more prevalent, but also less likely to induce depression in collectivistic East Asian cultures. The study took data from 29 countries, and found a consistent trend towards this same genetic variant being strongly associated with episodes of major depression in Western cultures.

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.
