modelling nVIII tuning curves

["Clifford (Kip) Keller" <kip@xxxxxxxxxxxxxxxxx>]

Hello,

    I wonder if anyone has a standard formula they use to model
roughly V-shaped VIII nerve tuning curves.  My problem is, I guess,
that they are only roughly V-shaped.  I work on barn owls, and I have
gleaned values for Q10dB, Q40dB, high frequency and low frequency
slopes (assuming linearity) from the paper by Christine Koppl (J Neurophys '97).
However, because the arms of the 'V' are not linear, using the slopes to
construct a tuning curve results in too high a Q-value.
  So I wonder how others deal with this problem.  Thanks for you
time.
