Dose-dependent changes in crayfish exploratory behaviors over a 40 min period as a function of infusions of amphetamine into the systemic circulation (A) or the supraesophageal ganglion (B). Results are expressed as changes in mean percent-age of time (±SE) spent in each behavioral category compared to saline. Significance levels from post hoc tests are listed as *P < 0.05, **P < 0.01, ***P <0.001.
