<span>This might disrupt the ability of a neuron to fire and action potential. If the influx of positive ions is blocked the neuron will not reach the necessary threshold required to fire an action potential. Since an action potential only fires when the neuron reaches the correct voltage threshold even a small increase in the number of positive ions entering the neuron might block it from firing an action potential.</span>
The answer is D Zika
