Figure 3: Alert behaviors
The frequency of the behavioral sequence (namely alert behavior) of the EGF-treated monkey was measured before (filled bar) and after risperidone treatment (RIS; 0.05 and 0.10 mg/kg: dotted bars). The same measurement was done for a reference monkey (open bar). Bars represent mean ± SEM. *P < 0.05 compared with a reference monkey and +P < 0 .05, between before and after risperidone treatment of an EGF monkey, both by two-tailed t-test (n=3 observations).
