Some central cholinergic effects have been reported in animals after acute exposure to radiofrequency electromagnetic field at low intensity. We studied acetylcholine (ACh) release in the brain of freely moving rats exposed for 1 h during the day to a 2.45 GHz continuous wave radiofrequency field (RF) (2 or 4 mW/cm(2)) or exposed for 1 or 14 h during the(More)
Huperzine A (HUP), an alkaloid isolated from the Chinese club moss, Huperzia serrata is a reversible inhibitor of cholinesterases which crosses the blood-brain barrier and shows high specificity for acetylcholinesterase (AChE) and a prolonged biological half-life. We tested, in vivo, its efficiency in protecting cortical AChE from soman inhibition and(More)
Soman, an anticholinesterasic neurotoxic drug, induces epileptic seizures during severe intoxication. The neuropathological lesions then observed are linked to the appearance of these seizures, but their trigger conditions still remain unknown and a great variability between animals is observed. We have developed a technique allowing, in freely moving rats,(More)
Soman, an anticholinesterasic neurotoxic drug, induces epileptic seizures during severe intoxication. Their trigger conditions still remain unknown and a great variability between animals is observed. The butterfly model in the catastrophe theory has been used to explain these triggering conditions. We have developed a technique allowing, in freely moving(More)
