Intelligence Tests

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]

all about the brain

Allen Human Brain Atlas - Brain Explorer 2 is a desktop software application for viewing the human brain anatomy and gene expression data in 3D. "Until now, a definitive map of the human brain at this level of detail simply hasn't existed," said Allan Jones, the nonprofit institute's chief executive. "For the first time, we have generated a comprehensive map of the brain that includes the underlying biochemistry." | Functional Neuroanatomy | 10 Great Sites for Reviewing Brain Anatomy | Harvard Brain Atlas.

A Few Strange Notes About Schizophrenia

Here's a strange one for the books: Science has taken notice that a really, really LARGE proportion of schizophrenic patients smoke. In fact, Scientific American Mind reports that an average of 85% of schizophrenic patients smoke cigarettes compared to only 20% in the general population. Many schizophrenics also appear to have abnormal thermoregulation, an impaired ability to understand body language, an inability to perceive an optical illusion called "the hollow mask illusion," an impaired ability to produce a brain protein known as the muscarinic M1 receptor, and an abnormally large number of genetic mutations known as CNV's or "copy number variations."

The Neurobiology of Birdsong

The universal grammar of birdsong is genetically encoded. "A new study, published online in the journal Nature, shows that the songs of isolated zebra finches evolve over multiple generations to resemble those of birds in natural colonies. These findings show that song learning in birds is not purely the product of nurture, but has a strong genetic basis, and suggest that bird song has a universal grammar, or an intrinsic structure which is present at birth."

Remember to Forget

Dr. Joe Z. Tsien has previously created a strain of mice unable to form memories, one with much improved memory - "Doogie" mice - and can now erase single mouse memories. "Our work reveals a molecular mechanism of how that can be done quickly and without doing damage to brain cells." Remembering to forget....
