Fig. 6. The serial effects of
-CTx MII,
-CTx AuIB and Mec are
additive and not the result of gradual deterioration of the preparation. (A)
Actual optical traces, spatially averaged over the entire ganglion from the
experiment in Fig. 5, are shown
instead of bars to highlight the progression of the drug effects. Here, all
the trials recorded during the experiment are shown. Note the obvious
clustering of responses according to colour. (B) Inhibitory effects on evoked
synaptic responses (spatially averaged over the whole ganglion) of sequential
application of nAChR-antagonists. (C) Examples of differential sensitivity of
individual neurones to these antagonists. As in
Fig. 5, all traces were
band-pass filtered between 6.6 and 200 Hz.
