It has been proposed that the post-ictal state is associated with the expression of hypoalgesia. It is clear that the projections among the periaqueductal gray matter (PAG), dorsal raphe nucleus (DRN) and locus coeruleus (LC) play a role in pain management. These mesencephalic structures have direct reciprocal opioid and monoaminergic projections to the LC(More)
Generalised tonic and tonic-clonic seizures are followed by significant increase in nociceptive thresholds in both laboratory animals and humans. The endogenous opioid peptides play a role in antinociceptive signalling, and the periaqueductal grey matter (PAG) is recruited to induce analgesia. Thus, the aim of this investigation was to evaluate the role of(More)
The electrical and chemical stimulation of the dorsal periaqueductal grey matter (dPAG) elicits panic-like explosive escape behaviour. Although neurons of the ventromedial hypothalamus (VMH) seem to organise oriented escape behaviour, when stimulated with excitatory amino acids at higher doses, non-oriented/explosive escape reactions can also be displayed.(More)
