Values are means ± SE; n, no. of neurons.
18β-GA, 18β-glycyrrhetinic acid; sEPSC, spontaneous excitatory postsynaptic currents.
The 20-μm concentration of 18β-GA significantly decreased the frequency of sEPSCs of DL neurons (P = 0.025). None of the other properties was significantly altered by 18β-GA.
