We investigated the response of alpha (4) nAChR subunit knockout mice to the gamma-aminobutyric acid (GABA) receptor antagonists; pentylenetetrazole (PTZ) and bicuculline (BIC), the glutamate receptor agonist kainic acid (KA), the glycine receptor antagonist strychnine and the K (+) channel blocker 4-aminopyridine (4-AP).

However, increasing neuronal excitability by application of 4-aminopyridine after pretreatment of the slice with blockers of (RS)-alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)/kainate, gamma-aminobutyric acid (GABA)(A) and glycine receptors evoked repetitive Ca2+ waves in dorsal horn.

The glycine receptor antagonist strychnine (4 microM) and the GABA (A) receptor antagonist bicuculline (10 microM) diminished and abolished, respectively, field population spiking and both antagonists reduced the power of 4-12 Hz oscillations.

Rhythmic alternating patterns elicited by tetraethylammonium on ventral roots were relatively stereotypic, had limited synergy with fictive locomotion induced by dorsal root stimuli, and were not accelerated by 4-aminopyridine.
Rhythmic alternating patterns were suppressed by blockers of glutamate, GABA (A) and glycine receptors, disclosing a background of depolarizing bursts inhibited by antagonism of group I metabotropic glutamate receptors.

These results suggest that, in addition to an action on the postsynaptic glycine receptors, zinc may depolarize the presynaptic nerve terminals, leading to an activation of voltage-dependent Na (+) and Ca (2+) channels that in turn increases glycine release.
