Figure 6. P/Q-type Ca++ channels mediate evoked miniature events at older ages.

Figure 6

A) (Left) Example current trace collected after 100 Hz stimulation (P12 cell), showing reduction in sPSC frequency after application of the P/Q-type antagonist ω-agatoxin IVA. (Right) Superimposed sPSCs (150 events) in control and in ω-agatoxin IVA, for the neuron shown in left; average traces in black. B) Mean frequency, but not amplitude or rise time, of sPSCs was affected by P/Q-block with ω-agatoxin IVA. Black lines connect control and drug measurements from individual cells. Cell in A shown in gray.
