Vision
? That's right. New theories of #FND from 
#neuroscience (especially #PredictiveCoding) suggest the symptoms of these disorders can be traced to basic brain processes, and will extend to other areas. We tested this remarkable hypothesis. 2/6pic.twitter.com/oKBOeWXT4b

We looked at 4 aspects of vision:
#attention,#expectations,
visual sensitivity
, & #metacognition - updating an ingenious task first designed by@maxine_sherman@anilkseth Adam Barrett +@kanair 3/6pic.twitter.com/56fGCELqSs

Thanks to the incredible
#MovementDisorder community in#Melbourne we were able to test 20 patients with#FND, 20 patients with organic movement disorders, & 20 carefully matched control participants. Without their help this wouldn't have been possible

So what did we find?
#attention#metacognition and#expectations were the same between#FND and control participants... But
visual sensitivity
not so much. Watch the animation below for details #scicomm 5/6pic.twitter.com/MsdfQ6Sxz1Prikaži ovu nit -
We take this as evidence for a difference in visual processing
between people with motor disorders (#FND or otherwise) and people that are similar to them in the general population. It's early days yet... But maybe those theories from
#neuroscience are onto something!

One final note - all of the
#Matlab &#Rstats code used in this study is openly and freely available for others to use. We've also made all of the (de-identified) data for every participant available.
