Figure 7. The average mean latency to locate a submerged platform in the MWM test over four weeks. Mice received daily injections of scopolamine (1 mg/kg, s.c.) or cannabis extract (5, 10 or 20 mg/kg) and were tested three times weekly. Asterisks indicate significant change from the saline control group. The plus sign indicates significant change from the scopolamine + cannabis 20 mg/kg group.
