摘要：

A decrease in the latency for the overt display of limbic seizures following the systemic injection of lithium and pilocarpine is weakly associated with enhanced global geomagnetic activity (in nanoTesla; nT). To determine the optimal threshold in global geomagnetic activity that is required for this effect, the seizure onset times for over 300 rats were dichotomized according to successive 5 nT increments. The results suggested that the seizure process occurred about 12% more quickly when the average daily global geomagnetic activity exceeded 20-25 nT and is commensurate with the observations by other researchers.
