Tetrodotoxin is a toxin that blocks voltage-gated sodium channels. What effect does this substance have on the function of neurons?

▸ The toxin does not interfere with neuron function because the voltage-regulated sodium channels would still function.

▸ Neurons depolarize more rapidly.

▸ Action potentials lack a repolarization phase.

▸ The neuron is not able to transmit action potentials.

▸ The absolute refractory period is shorter than normal.
