Figure 9 shows ambulatory distance traveled within the first 30 minutes of the drug expression session. Experimental subjects injected with AVP 4-9 at 1ng dose traveled greater ambulatory than MC 1ng, 15 ng and vehicle subjects (***, p<0.001). AVP 4-9 at a 15ng dose traveled a greater ambulatory distance than MC 1ng, MC 15ng and vehicle subjects (###, p<0.001). MC at 15ng dose traveled a greater ambulatory distance than MC 1ng dose subjects (ΔΔΔ, p<0.001). Vehicle treated subjects traveled a greater ambulatory distance than MC 1ng subjects (+++, p<0.001). No significant difference was found between AVP 4-9 1ng and 15ng and between MC 15ng and vehicle (p>0.05).
