Locomotor activity in Poria cocos-, Polygonatum sibiricum-, and Gastrodia elata-treated flies. Representative activity record (actogram) of a single fly from each treatment group. (A) Typical actograms of flies following doses of P. cocos (n=16), P. sibiricum (n=16), G. elata (n=16), and the control (n=20). Average activity was measured at 30-min intervals for 5 days. Black/white bars on top of the actograms indicate night (22:00 to 10:00) and day (10:00 to 22:00). (B) Activity during subjective day and night. Values are the means±SEM for each group. *Significant differences at P<0.05 using Student’s t-test.
