[The effect of electrostimulation of the locus coeruleus, the medial parabrachial nucleus and the dorsal raphe nucleus on the paired activity of the respiratory center in rats].

Using the electromyographic method in acute experiments on anaesthetized with urethanum rats the different influence of locus coeruleus, nucleus medialis parabrachialis and nuclei raphae on respiratory centre activity has been established. The effect of the locus coeruleus depended on parameters of stimulation and on the character of the tested structures between each other and the bilateral regions of the respiratory centre.
