Figure 6

Effect of GV20 acupuncture stimulation on the percentage values of the mean (±standard errer, SE) number of brain-derived neurotrophic factor (BDNF) and cAMP-response element-binding protein (CREB)-stained neurons in various hippocampal area after the Morris water maze (MWM) task (n = 3-4/group). Representative photographs and relative percentage values are shown in (A) and (B), respectively. (a): BDNF expression in the SAL group, (b) BDNF expression in the SCO group, (c) BDNF expression in the SCO + GV20 group, (d) CREB expression in the SAL group, (e) CREB expression in the SCO group, (f) CREB expression in the SCO + GV20 group. Sections were cut coronally at 30 μm. Scale bar represents 50 μm. ^** p < 0.01, ^*** p < 0.001 vs. the SAL group; ^# p < 0.05 and ^## p < 0.01 vs. the SCO group.
