Points represent the mean and error bars represent the standard error of the mean. Top panel shows drug-appropriate responding of the test compounds. The x-axis represents dose of MDL100907. The y-axis represents percentage of drug-lever appropriate responding. Bottom panel shows rate of responding as responses per second as a function of dose. Open circles- saline control; Open diamond- drug control. N=7. Asterisk indicates points that are different from the drug control.
