“Application of high potassium media to growth cones inhibited neurite outgrowth, an effect that was blocked by 2 mM cobalt or 100 μM cadmium, suggesting that calcium influx via voltage‐gated channels contributes to glutamate‐induced regulation of neurite outgrowth.”
“When the non‐specific calcium‐channel blockers cobalt or lanthanum were included in the stimulation buffer with potassium , the release of [3H]d‐aspartate was decreased by about 40%.”

“The present study has been performed to test for effects of … on electrical properties of cultured subconfluent kidney (MDCK)-cells: cobalt (10 microM) leads to a rapid, sustained and reversible hyperpolarization of the cell membrane, paralleled by an increase of the potassium selectivity and a decrease of the resistance.”
“Thus, cobalt enhances the potassium conductance in a calcium dependent way.”
“Thus, cobalt increases the potassium conductance of the cell membrane.”
“The inorganic calcium channel antagonists, cadmium and cobalt , but not magnesium, zinc, manganese or lanthanum, significantly inhibited the 40 mM potassium chloride-induced stimulation of the binding of [3H]HCh-3 in the striatum.”
“Deletion of calcium and the substitution of cobalt (10 mM), resulted in a significant reduction in both resting release and the release otherwise evoked by the addition of potassium.”
“The potassium evoked release of VIP-LI and CCK-LI was inhibited by the substitution of cobalt (4 mM) for the calcium ion in the perfusion media; basal efflux was not affected.”
“ Potassium (60 mM) induced an increase in IRS secretion which was dependent on extracellular calcium concentration and could be prevented by the addition of the calcium channel blockers, cobalt or verapamil.”
