Figure 4. BK channels also negatively regulate transmitter release at this synapse.

Figure 4

a, representative traces of eIPSC recorded at a holding potential of −90 mV before (left panel) and after incubation (right panel) with 100 nM Iberiotoxin (IbTx), a specific BK channel antagonist. The inset shows that IbTx did not affect the amplitude of sIPSC, also recorded at a holding potential of −90 mV.
