The typical protocol for revealing them, either by macroscopic currents or dye uptake\\leakage, involves reduced extracellular calciumion and prolonged depolarization. Simplified reaction-diffusion equations for potassium and calciumion concentrations during spreading cortical depression. Activation with low external calciumion and long depolarizing voltages is a consistent feature of plasma membrane hemichannels. The gas-solid difference of calciumion charge state distribution has been numerically demonstrated. The inactivation caused by intracellular calciumion accumulation and the voltage dependency of activation is responsible for the bell-shaped dependency. At high agonist concentrations (when glutamate receptor occupancy was very low), the channel was either conducting, or if a calciumion was bound, nonconducting. This is not to say that calciumion is not involved or an important modulator of effects on connexin channels. In a further experiment (experiment 3) we observed changes in the ultrastructural distribution of intracellular calcium deposits in oocytes in which the calciumion channels had been blocked by verapamil. The calciumion content in the water ranged from 7 to 28 mg l21, so that the shell height of adult snails scarcely reached 8 mm. A potential triggering step is that the close approach of the extracellular domains of the hemichannels displaces a postulated calciumion(s) that keeps the extracellular end sealed. Also, annexins have been shown to be involved in trafficking and organization of vesicles, exocytosis, endocytosis and also calciumion channel formation.

For example, microfluorimetry is used in neurons to compare the effects of neurotoxins on both calciumion concentration and mitochondrial membrane potential in individual cells.

During suppression, neuronal pumps restore the calciumion concentrations to normal levels, thus causing the cortex to be subject to the process again.

When in solution, the calciumion varies remarkably to the human taste, being reported as mildly salty, sour, mineral-like or even soothing.

So long as internal calciumion concentrations remain at an elevated level, the neuron will continue to undergo periods of rapid spiking.
