Fig. 10. Excitatory junction potentials (EJPs) inhibited by the opener inhibitor
(OI) (left: interstimulus interval 52 ms, OI precedes OE) and by the common
inhibitor (CI) (right: CI and OE stimulated simultaneously) superimposed on
the EJPs recorded in the absence of inhibitory stimuli (broken lines). In
these examples, OI inhibited the area under the EJP by 75.9% and the amplitude
of the EJP by 29.7%. CI inhibited the area under the EJP by 49.8% and the
amplitude of the EJP by 16%. Scale bar on left, 2 mV, 200 ms; scale bar on
right, 1 mV, 200 ms.
