In previous research, we have found that acute exposure to a 60 Hz magnetic field decreased cholinergic activity in the frontal cortex and hippocampus of the rat as measured by sodiumdependent high-affinity choline uptake activity. We concluded that the effect was mediated by endogenous opioids insi
