More than 30 000 brain scientists are in Washington  D.C.  this week attending the Society for Neuroscience meeting. One of the hot topics this year is mental disorders such as depression and schizophrenia and autism.  NPR science correspondent Jon Hamilton  has just come from the meeting to talk about some of what  he 's been seeing and hearing. Hi  John. Thanks for coming.
 JON HAMILTON   BYLINE: Hi.
 HAMILTON : Twenty years ago  I'd say it didn't contribute much  but things are really changing. And I was really surprised. I was going through the abstracts to this year's meeting  and there were nearly a thousand papers that mentioned depression. There were 500 that mentioned schizophrenia or autism. And just this morning  there was this study on how - looking at the brain tissue of people with obsessive compulsive disorder and how it's different.
MARTIN: That's NPR's science correspondent Jon Hamilton. Jon  thanks so much.

With his move from the Washington Post to CNN   Chris Cillizza  went from a dishonest leftwing news outlet to one with no scruples whatsoever.
CNNâs sins range from flat-out lying to ginning up violence in predominantly black neighborhoods to pointing what looks like a sniper scope at President Trumpâs office window. And with this move   Cillizza  has become even more dishonest than he was at the Post.
Back in July  although his very own network had already dishonestly described a meeting between Trump and Russian president Vladimir Putin as âsecret â  Cillizza  still published a piece branding Trump a liar over his claim that the media was dishonestly describing the meeting as âsecret.â
Eager to exploit Sundayâs mass-slaughter in Las Vegas for the cause of gun control   Cillizza  published a brand new series of lies this week  with the provably false claim that neither Hillary Clinton nor Barack Obama have ever advocated for gun confiscation laws.
Moreover   Cillizza  again brands Trump a liar for claiming that they have.
