Fig. 11. The refractory period matches the duration of the low-responsiveness
window. Averaged spherical cell responses obtained from 10 series of current
test steps of constant intensity applied at different delays after a
conditioning spike (traces) are superimposed on the amplitude of the
magnocellularis nucleus responses to the conspecific-generated EOD shown in
Fig. 2, normalized as a
percentage of the amplitude of the self-generated EOD (black circles). (A)
In vitro test step at 400 pA, conspecific located antiparallel at 6
cm; (B) in vitro test step 430 pA, conspecific located antiparallel
at 3 cm. Resting membrane potential –70 mV, conditioning step 500 pA. In
order to compare both graphs, zero magnocellularis response was aligned with
the critical depolarization level and 100% magnocellularis response with the
largest spike provoked by the self-generated EOD (right axis).
