Figure 4. Antagonism of dopamine-induced inhibition of GABAA IPSCs by sulpiride.

Figure 4

A, superimposed IPSCs show that the dopamine D2 receptor antagonist sulpiride (1 μM) blocks the inhibitory effect of dopamine (100 μM) on the GABAA receptor-mediated synaptic current. B, averaged data from 6 cells showing that sulpiride (1 μM) reverses the reduction in IPSC amplitude produced by dopamine (100 μM). Data were normalized to the amplitude of the first synaptic current evoked in each cell.
