A couple of great blog carnival editions (collections of blog posts around specific topics):

- Encephalon: neuroscience and psychology.

- Grand Rounds: health and medicine. 

And a good Radar Roundup of brain-related news. Note: our estimate for the whole market in 2007 is $225m, not $110m; and the Consumer Segment (mostly Nintendo Brain Age/ Academy, but not all) accounts for $80m.
