In terms of an individual neuron's excitability, what would be the consequence of a drug that reduced the ability of voltage sensitive sodium ion channels at a neuron's axon hillock open up?
What will be an ideal response?
Since this would inhibit sodium flow rapidly into the axon, the neuron's excitability, i.e., its ability to create action potentials, would decrease.
