This talk at MIT a few days ago measured nervous system disruption in rident guts with autism analogs. http://calendar.mit.edu/event/exploring_gut-brain_signaling_in_autism#.YZlNmy1Haf0 http://calendar.mit.edu/event/exploring_gut-brain_signaling_... The conclusion is both the gut and brain may be affected by whatever causes autism. But the study didnt attempt to establish whether the gut affected the brain, or the brain affected the gut, or were they simultaneous.
