In conclusion, the comparative effectiveness of strychnine and DCKA can be used to distinguish between the alpha1, alpha2 and alpha2* receptor responses.

The majority (60/71, 85%) of neurons tested were hyperpolarized by NA application, and these hyperpolarizing effects were mimicked both by the alpha (2) adrenergic agonist, clonidine (18/28, 64%) and the beta adrenergic agonist, isoproterenol (9/24, 38%).
NA-induced hyperpolarizing effects were maintained in the presence of tetrodotoxin (TTX), 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX), d,l-2-amino-5-phosphonopentanoic acid (AP5), picrotoxin and strychnine, a Na (+) channel, ionotropic glutamate receptor, GABA (A) and glycine receptor antagonists, respectively, indicating that the effects of NA are direct on the postsynaptic SG neurons.

Patch-clamp electrophysiological recordings revealed that the alpha1 or alpha2 glycine receptor subunits expressed in these cells form functional glycine receptors that are inhibited by strychnine and picrotoxin.
In order to measure expression of the glycine alpha1 or alpha2 receptor protein, we produced a new anti-alpha1/alpha2 glycine receptor antibody (anti-alpha GR).

Activation of spinal alpha (2)-adrenergic receptors by the descending noradrenergic system and alpha (2)-adrenergic agonists produces analgesia.
The miniature excitatory postsynaptic currents (mEPSCs) were recorded in the presence of tetrodotoxin, bicuculline, and strychnine.

The present study seeks to describe some of the intrinsic properties of bulbospinal C1 cells and to establish whether they have alpha 2-adrenergic inhibitory "autoreceptors." RVL bulbospinal cells (retrogradely labeled with microbeads) were recorded in thin slices from 3- to 7-day-old rats with patch electrodes containing Lucifer yellow.
Blockade of fast postsynaptic potentials with kynurenic acid plus bicuculline plus strychnine or with a low-Ca (2+)-high-Mg2+ medium failed to reduce their firing rate.

Both alpha1- and alpha2-receptor activation influences the GABAergic pathway controlling the duration of swimming episodes and is involved in the glycinergic modulation of the swimming rhythm and its longitudinal co-ordination, with alpha2-receptors additionally affecting swimming frequency through GABAergic pathways.
We show that NA could still modulate aspects of swimming after blocking either glycine or GABA (A) receptors with strychnine and bicuculline, respectively.

The glycine-receptor antagonist strychnine (25 micrograms, i.t.) did not modify the hypotension induced by either noradrenaline (in the presence of prazosin) or adrenaline.
The hypotensive responses induced by low doses of i.t. injected catecholamines seem to involve the activation of spinal alpha 2A-adrenoceptors and the stimulation of an inhibitory GABAergic neuron in the spinal cord.

Intrathecally administered strychnine and the GABAA antagonist bicuculline also induced allodynia in conscious mice.
