Fig. 3. NaBenz/D-serine together suppressed aversion-resistant alcohol intake.
(A) The combination of ineffective concentrations of D-serine and NaBenz (dark purple, n=27) significantly reduced compulsion-like drinking. (B) The NaBenz/D-serine combination did not reduce alcohol-only intake (light purple, n=12). Dser: D-serine; NaB: NaBenz. *** p<0.001 for NaBenz/D-serine versus other conditions.
