  I was online looking for example of disorders associated with corollary discharge other than just car sickness and.  I actually found a couple of article and a student web paper from 2003 (/bb/neuro/neuro03/web2/mcoleman.html) that were on corollary discharge and schizophrenia.  From what I have been able to gather corollary discharge comes into play with individuals who have positive schizophrenic symptoms particularly auditory hallucinations.  Apparently for individuals with schizophrenia their corollary discharge does not work properly and they have trouble distinguishing covert speech, thoughts, from overt speech, things that are actually said.  I have never really though about it until this point but it would be really difficult and scary if you could not determine your thoughts from what you were actually saying!  Imagine thinking something terrible about a friend’s new hair cut and not realizing whether you were thinking it or actually saying it!

I think, further, this may have implications (as posted earlier) for perception.  If your corollary discharge is not working property there are huge implications on many levels.  Also, humans are all very different so I wonder if there are minute differences in our corollary discharge that actually cause us to experiences things different, not having as large an implication as in schizophrenia but still having an effect….just more to ponder…and to be thankful that as far as I know my corollary discharge is just fine, thank god!
