Re: Microelectrode recordings before pallidotomy

[Alicia Saenz de Cabezon <asaenz@REDESTB.ES>]

I haven't got experience with microelectrodes, I'm sorry, but I would like
to put another question to you or anyone in the list: what do you think
about the transient evoked otoacoustic emission screening for the risk
newborn? Are they really useful? Are we the clinical neurophysiologists who
must do it? Neonatologists in my hospital are asking to us for this test,
but in the bibliograghy it seems to be done by audiologists instead.
Besides, as I have read the BAEP are more useful because there is a high
rate of false negatives with the otoacoustic emissions. I would like to
read your opinions.
Thank you very much

I am interested in microelectrode recordings of relevant brain
regions prior to pallidotomy for Parkinson's disease. Could you
please advise me about the technical and practical aspects of the
procedure?
Some centres doing pallidotomy do not perform microelectrode
recordings. Clearly there is a difference of opinion amongst
different centres. What does the discussion group think?
