Study of the neural basis of striatal modulation of the jaw-opening reflex.

Previous experimental data from this laboratory demonstrated the participation of the striatum and dopaminergic pathways in central nociceptive processing. The objective of this study was to examine the possible pathways and neural structures associated with the analgesic action of the striatum. The experiments were carried out in rats anesthetized with urethane.

Basal ganglia and functions of the autonomic nervous system.

1. The aim of this mini-review was to describe an underrecognized but important aspect of the basal ganglia diseases, the dysfunction of the autonomic nervous system that patients suffer owing to the degenerative process affecting these structures, mainly Parkinson's disease. 2.
