mRNA levels of those GABAA receptor subunits that were significantly reduced by the GABA uptake blocker (NO-711) in the PF region only. For these subunits, NO-711 and gabazine exerted opposite effects in the PF region, whereas their effects in the DM region were not significant. The data were obtained from 8 half-slices superfused with neutral medium (ACSF), and 6 pairs of half-slices of which one was superfused with NO-711 and the other with NO-711+gabazine. * p<0.05, one-way ANOVA; **p<0.05, paired t-test.
