I am looking for some values describing the amount of oxygen for a single 
neuron. I still run in problems to convert the blood oxygen level into the 
real oxygen level necessary for the survival of a single neuron. Actually I 
could find only very few data about the oxygen level in brain tissues, 
which might be around 40 mmHg, if this is true. The problem is, that the 
oxygen should diffuse from the blood vessel to the neurons, sometimes at a 
distance as long as 400 Ám. So it is difficult to estimate. Moreover I have 
problems to convert the partial pressure (mmHg) of oxygen into mg/L. I 
would be really happy if somebody can provide me some data of the required 
oxygen level in mg/L or PO2 or at least send some reference where to check.

With my best regards

Tom
