title: Selective activation of striatal output nuclei by organophosphorus intoxication in the rat: EEG and 2-deoxy[3H]glucose metabolic mapping.
abstract: Central effects of paraoxon (an organophosphate, inhibitor of acetylcholinesterase) treatment were investigated using 2-deoxyglucose (2-DG) and EEG methods. Six rat brain structures (external globus pallidus, ventral anterior nucleus of thalamus, entopeduncular nucleus, substantia nigra pars reticulata and superior colliculus) presented an increase of 2-DG labelling after acute injection of this toxic compound. The EEG recordings showed hippocampal slow theta rhythm which preceded an increase of cortical rhythm frequency. Rats with 2-DG mapping modifications presented also EEG seizures.
