In the present paper, the action of beta-phenylethylamine on electrophysiological activity of dopaminergic nigrostriatal neurons is described. 10 s after its i.v. injection and during 2-4 min, beta-phenylethylamine decreased the firing rate, the number of spikes within and out of burst and the number of bursts per second of these neurons. This was a(More)
The present paper describes the effect of beta-phenylethylamine and its metabolites phenylethanolamine, tyramine, acetyl-phenylethylamine and phenylacetaldehyde on the dopaminergic nigrostriatal system. The rotational behavioural response to the i.v. injection of these drugs was quantified in animals with a unilateral 6-hydroxydopamine lesion of the(More)
This is an simple, non-time-consuming and advantageous procedure for catheterization and drug administration in thin arteries of small animals. The cannulation method consists of implanting polyimide-coated silica capillary tubing. To avoid vascular tear during puncture, the tubing tip is beveled. The cannula is stuck to the wall of the artery without(More)
