The latest edition of Encephalon is now up at the Mind Hacks blog. It is a very good collection of neuro articles and there is lot of good stuff to drool at.
I especially liked the Neurocritic article on correlation between the spontaneous activity in fMRIs and slow wave EEG signals- we know that it is an important phenomenon, but what all this spontaneous activity signifies is still unclear. I also like Pure Pedantry commentary on the finding that tow subregions of dlPFC are implicated in hypothesis-generation. He raises important points regarding what three conditions a brain area should show before we jump to concluding that that area is indeed responsible for a particular function.
There is plenty of other interesting stuff including A Michael Posner interview, a report on selectively erasing memories in mice and a controversial post on whether more gesture usage implies slower linguistic learnings and capabilities in children; so head on to the Encephalon and get your kicks!
