Serotonin neuron-dependent and -independent reduction of dyskinesia by 5-HT(1A) and 5-HT(1B) receptor agonists in the rat Parkinson model.
5-HT(1) receptor agonists have been shown to reduce abnormal involuntary movements (AIMs) in the rat and monkey models of l-DOPA-induced dyskinesia. Different mechanisms have been proposed to underlie this effect. Activation of pre-synaptic 5-HT(1) receptors has been suggested to inhibit dysregulated release of dopamine from the serotonin terminals, and thus, abnormal activation of striatal dopami
