The effect of khc mutations on excitatory junctional currents evoked by direct electrotonic stimulation of the presynaptic terminal. Terminals were stimulated (triangles) and recordings of EJCs were taken from muscle 6 of segments A2 and A6 of control and khc mutant larvae. The bathing solution contained 1 μM tetrodotoxin. Stimulation parameters were 5 V and 1 ms.
