TITLE passive membrane properties for GPi

COMMENT

Nakanishi1990 measured the average input resistances of EP neurons
  Type I  --> 126 MOhm (8.9286e-9 mho)
  Type II --> 145 MOhm (6.8966e-9 mho)
All recordings were at 36degC, so there is no need to add a temperature
correction factor.  Note that if simulation involves Cs+ or TEA, it is
necessary to adjust gpas accordingly (See Fig1D).
