"acupuncture stimulation at P6 increased AchE (acetylcholinesterase) chemical reaction activity in the brain.
AchE is an enzyme that converts the neurotransmitter acetylcholine into choline and acetate and plays an important role in synaptic transmission. The study shows that rats exposed to chronic mild stress (CMS) had significantly lower AchE activity in the hippocampus of the brain. It was discovered that acupuncture at P6 increased chemical reactivity of AchE in the hippocampus compared with the control group.
The researchers also conducted a passive avoidance test (PAT) to compare the biochemical findings with behavioral examination. The acupuncture group performed better than the control group for the PAT. The researchers concluded that acupuncture at P6 improves memory, increases AchE reactivity in the hippocampus and restores learning and memory after biochemical and behavioral impairments due to chronic mild stress."
