Fig. 2. Power spectra obtained from experiments with (A) NaCl Ringer as the mucosal
and serosal bathing solutions, (B) NaCl Ringer as the serosal solution and KCl
Ringer as the mucosal solution and (C) NaCl Ringer as the mucosal solution and
KCl Ringer as the serosal solution. Note the presence of two Lorentzian
components in C. The spectra from A and B are from sequential treatments of
the same preparation as depicted in Fig.
1. Sf, spectral density. The arrows on the
spectra indicate the range of data points selected for the computer fit of the
spectra using equation 1.
