sulfonylurea's exert their activity by blocking KATP channels in A3/4 cell membrane to depolarize it, which leads to activation of voltage-gated calcium channels to enable Ca+2 influx for enhancing intracellular calcium levels.
How a group of brain cells depolarize at exactly the same time is a mystery, since it cannot be explained by physical connection between those cells.
One drawback is that AC can depolarize the zinc grounding cell allowing more cathodic protection current to pass through the cell.
Automaticity means that a cell is able to spontaneously depolarize and respond electrically.
The cell will remain at that resting potential until it is either driven to response by another pacer or can slowly rise to a point where it can spontaneously, automatically, depolarize.

Upon stimulation, the characean plasma membrane depolarizes to approximately 0 V.
When these receptors are activated, they open up and depolarize the nerve cell, which transmits an attention-grabbing pain signal through the spinal cord to the brain.
Although it is likely that stretch depolarizes the neuronal processes, as is well documented for crustacean stretch receptors (e.
By blocking bcl-2 dimerization (bcl-2/bcl-2) and producing a bcl-2/A[beta]42 complex, A[beta]42 removes the protective effect of bcl-2, the mitochondria depolarizes and releases cytochrome c; a cytosolic trigger for apoptosis.

This, together with electrophysiological evidence that taurine depolarizes the MNN neurons in a manner consistent with that of the endogenous neuro-transmitter, provides compelling evidence that taurine, or a taurine-like molecule, is the neurotransmitter in Cyanea.
