Effect of GV20 acupuncture stimulation on latency to enter the dark compartment in the acquisition trial and the retention test in the passive avoidance test (PAT). The rats were randomly divided into five groups of six or seven individuals as follows: normal group (SAL group, n = 7), the SCO-induced and saline-treated group (SCO group as a control, n = 7), the SCO-induced and Baihui (GV20) acupoint-stimulated group (SCO + GV20 group, n = 7), the SCO-induced and Yangji (TE4) acupoint-stimulated group (SCO + TH4 group, n = 6), and SCO-induced and non-acupoint (on the tail)-stimulated group (SCO + TA group, n = 6) every day for 5 min before SCO injection. *** p < 0.001 vs. the SAL group; # p < 0.05 vs. the SCO group.
