Fig. 1

Abscissae: frequency of electrical brain stimulation in log Hz. Ordinates: percent maximum control reinforcement rate (%MCR). Drug doses are indicated in legends in units of mg/kg. Filled points represent frequencies at which reinforcement rates were statistically different from vehicle rates as determined by two-way ANOVA followed by Holm-Sidak post hoc test, P<0.05. All data show mean ± S.E.M. for five (RTI-118) or six (cocaine, U69,593) rats.
