Acupuncture Rescues Cognitive Impairment and Upregulates Dopamine--Hydroxylase Expression in Chronic Cerebral Hypoperfusion Rats

Acupuncture ameliorates episodic memory deficits in new object recognition test. (a) Illustration showing the experimental design of the novel object recognition test. Sham: sham-operated group, Acu: acupuncture group, Pla-acu: placebo-acupuncture group, Sham + Acu: sham-operated + acupuncture group. (b) The new object recognition performance of rats during the familiarization, test 1 (3 hours after familiarization), and test 2 (24 hours after familiarization). The “recognition index” for the trials was calculated as follows: recognition index = time exploring novel object/(time exploring familiar object + time exploring novel object). (n = 6 rats for each group, : P<0.001, compared as indicated.)
