Descartes's errors and beta-blocker ?

[Etienne Pralong]

Hello,

I just read the book Descartes's errors and was impressed and convinced by
the theory of physical markers.
I was just wondering if some experiments have been performed where drugs which
are not supposed to enter the CNS like beta-blockers (some of them) but which
can reduced the strength of physical markers could impaired the process of of 
decision making ?

Thanks
