Baclofen modulation of P/Q type calcium currents.A, In the presence of 4 μm nimodipine, baclofen (20 μm) inhibition of the remaining non-LICa disappeared after agatoxin IVB (AgaTx, 500 nm) blockade of P/Q typeICa. B, Repeatable inhibition of IPSCs by baclofen (20 μm) disappeared after agatoxin IVB (500 nm), blocking most of the IPSC.
