[Electrocorticograms and the histochemical effects in the rat accompanying the reactivation of cholinesterases after the effects of an organophosphorus inhibitor].

Abstract

The administration of paraoxon, an organophosphate inhibitor of cholinesterases, elicits theta rhythms, fast rhythms and paroxystical alterations on the electrocorticogram of the Rat. The disappearance of these abnormalities of the cortical activity after administration of aromatic oximes seems to be in good correlation with the restoration of cerebral cholinesterase activity revealed by histochemical method.
