Figure 2. Effect of adolescent ethanol exposure on phasic GABAAR currents in layer V pyramidal neurons of the adult PrL-C.

A) Representative traces of IPSCs from adult PrL-C slice obtained from control and AIE exposed rats. Cells were voltage-clamped at -70mV. B) While the frequency was similar in slices from both control and AIE treated rats, spontaneous IPSC (sIPSC) amplitude was significantly reduced in slices from AIE exposed rats (n = 20-21 cells/group; **p = 0.004). C) Representative paired-pulse traces of evoked IPSC (eIPSC) currents from adult PrL-C slices obtained from control and AIE treated rats. D) The paired-pulse ratio (PPR) was not altered by AIE exposure (n = 8-9 cells/group). E) Representative traces of miniature IPSCs (mIPSC) from adult PrL-C slices obtained from control and AIE exposure rats. F) AIE did not alter either the amplitude or frequency of mIPSCs (n = 8-9 cells/group).
