Abstract

It has been reported in Medical Clinics that some patients report oscillations in the nociceptive threshold, a post-seizure phenomenon not yet widely investigated in Neuroscience field. Considering that some antiepileptic medicines cause analgesia as side effects, and taking in mind that the majority of epileptic patients is commonly treated since the first diagnose of epilepsy was made, this fact is a constant problem in the study of that post-ictal phenomenon. The aim of the present project is to investigate the muscarinic and nicotinic cholinergic neurotransmission in the post-ictal antinociception, specifically studying the role of some cholinergic output from the tegmentar pedunculopontine nucleus on serotonergic and noradrenergic neurons of some nuclei of the pain endogenous inhibitory system, such as the raphe magnus nucleus, dorsal raphe nucleus and locus coeruleus, in an experimental model of epilepsy in Rattus norvegicus (Rodentia, Muridae).
