Blogging on the Brain: April 22 - 29th 2006

The week in brain blogging reviewed:

Thanks to Neurodudes for pointing out a new book on the 23 problems facing systems neuroscience. I actually think we already have the answers to a few of these problems, but interesting nonetheless!

An interesting assessment of the current state of science blogging over at Science & Politics. Will we start seeing original hypotheses and unpublished data in the natural science blogosphere any time soon? An interesting question.

A really nice week over at Myomancy, with my favorite being this post about whether ADHD might be treated with ... coffee! There's also a nice update on the latest research in imaging the brains of those with ADHD.

Thanks to Intelligence Testing for alerting me to a popular article this week, "the intelligence gene." Like Kevin, I am a novice at behavioral genetics, but am nonetheless highly distrustful of any press release claiming to have found "the gene" for homemaking, good bridge playing, fondness for chocolate, much less a concept as complicated, heterogenous, and underconstrained as "intelligence."

A nice post & very well informed discussion over at Neurofuture on the orbitfrontal cortex, and a recent Nature paper.

Finally, nice coverage of recent developments in "brain training" for autism at the wonderful Neurocritic blog.

Have a nice weekend!

That's a book edited by van Hemmen and Sejnowski... David Hilbert lived quite a while ago.

Hey, Chris. I posted on that Intelligence gene silliness, too.

Here's the text of my post, only cus I am a slow typer and cut and paste is easier than reiterating. :)

I worded the title of this post exactly the same as one of the many press headlines for this story. Once again, an r-squared of .03 is blown completely out of proportion.

You gotta get to the end of the article, after all the hyperbole, to read this:

"While our data suggests the dysbindin gene influences variation in human cognitive ability and intelligence, it only explained a small proportion of it -- about 3 percent. This supports a model involving multiple genetic and environmental influences on intelligence,"

I think we oughta start looking for the 'gene for exaggeration' in a subpopulation of humans known colloquially as "Journalists."
