Figure 3. Other PKA activators mimicked the effect of forskolin on the glycine current.
A, outward current was elicited by application of 100 μM glycine alone (a), or by co-application of glycine plus 50 μM 8-Br-cAMP (b). B, outward current produced by application of 100 μM glycine alone (a) or glycine plus 500 μM IBMX. Neurones were voltage clamped at 0 mV.
