Encephalon #56

The 56th edition of the blog carnival Encephalon is out at Combining Cognits. Highlights: A Neurostimulating Blog on deep brain stimulation as a treatment of addiction; Jared Tanner at Brain Blogger on reduced empathy following traumatic brain injury; and Science Blog on why the insanity defense is unscientific (I'm not so sure I agree, but it's interesting).
