9409718 Straub H, Kohling R, Speckmann EJ: Strychnine-induced epileptiform activity in hippocampal and neocortical slice preparations: suppression by the organic calcium antagonists verapamil and flunarizine. Brain Res. 1997 Oct 31;773(1-2):173-80.

To test for this, the antiepileptic effect of the specific L-type calcium channel blocker, verapamil, in hippocampal and neocortical slices was investigated.

Several classes of compounds can modulate the PTZ discriminative stimulus including 5-HT (1A), 5-HT (3), NMDA, glycine, and L-type calcium channel ligands.

The electrophysiological data were obtained during rhythmic bursting produced by application of N-methyl-D-aspartate (NMDA) and strychnine to the isolated spinal cord at various postnatal ages.
These results demonstrate that in the spinal cord, the L-type calcium channel profile develops both physiologically and anatomically in the early postnatal period.

Voltage-dependent calcium channel (VDCC) antagonists are active in the forced swim test and in learned helplessness behavioral paradigms, suggesting their antidepressant efficacy.
We report that chronic administration of verapamil (20 mg/kg) and diltiazem (10 mg/kg) did not reduced OB-induced hyperactivity, although these drugs reduced the potency of glycine to inhibit [3H] 5,7-dichlorokynurenic acid (DCKA) binding to strychnine-insensitive glycine sites of the NMDA receptor complex.

Strychnine, the blocker of glycine receptors did not affect the initial peak but strongly decreased the oscillations frequency.
Light responses were inhibited by the calcium channel blockers cadmium ions and nifedipine, suggesting that the release of glutamate was calcium dependent.

Sighs were triggered by eupneic bursts under control conditions, but not in the presence of strychnine (1 microM).
Although all neurons received synaptic inputs during both activities, the calcium channel blocker cadmium (4 microM) selectively abolished sighs.

LTPgly could only be masked but not prevented by strychnine (100 microM) and remained undisturbed in the presence of picrotoxin (100 microM). 5.
As indicated by the inhibition of LTPgly of the fEPSP slope by the L-type calcium channel blocker nifedipine (20 microM), voltage-dependent calcium channels are the source for Ca2+ elevation as the intracellular trigger. 7.

The inhibitory potentials are abolished by strychnine and curare, respectively.

Freshly isolated rabbit erythrocytes were subjected to a hypotonic shock, and the protective effects of various calcium channel blockers, phospholipase inhibitors, free fatty acids, the NO-synthase inhibitor L-NAME, the amino acid glycine and its receptor-analogue strychnine, and two chloride channel blockers were examined.
