performed on the pair data indicates that most of the variability comes from differences in
the coupling between pairs, indicating that the recordings are consistent when the driver
and follower cell are reversed. This agreement in the reciprocal conductance demonstrates
not only that our technique is reproducible, but that there is an absence of any rectifying
element between the two cells.

While the network conductance between cells is an interesting parameter because it can
be measured directly, it is not useful in formulating a model of the rod network. However,
by knowing the network input impedance for a point source of current Ri∏2D and the nor-
malized length constant X∙2d∣D, the membrane resistance R_m and coupling resistance R_c
can be determined. For the dual patch experiments, R_m2D and λ2D∣D were determined ac-
cording to the assumptions and derivations given in section 5.5. It is important to note that
due to the difference in topology, values for Ri∏2D and λ2D∣D are different for the same R_c
and R_m in the one-dimensional network analyzed in section 5.2.

From section 5.5:

‰p = 137MΩ

X_2d∕D = 0.53

From figure 5.7 C, this corresponds to a ratio Ri_n2D∣R_m ≈ 0.5 and R_c∣R_m ≈ 3.4 which
means

<<   90   91   92   93   94   95   96   >>
