Effect of high pressure on synaptic response

[Etienne Pralong]

It is well known that high pressure of N2 are anesthetic. Does somebody know 
if the electrophysiological response of cortical neurones to high pressure 
(5-10 atmospheres) of gaz has been studied ?  I was wondering if a brave 
electrophysiologist has done this type of experiment in a high pressure 
chamber ?
