Noradrenergic modulation of glutamate-induced excitatory responses in single neurons of the red nucleus: An electrophysiological study

Although these data suggest some involvement of beta adrenergic receptors in the modulation of neuronal responsiveness to Glu, the overall results indicate a short-term depressive action of NA, mediated by alpha2 receptors, on the responsiveness of RN neurons and suggest that stress initially leads to an attenuation of the relay function of the RN.
