Answer:
1000/second
Explanation:
A nerve impulse is rise or fall of membrane potential in a certain region of a cell.
One nerve impulse lasts for 1 ms which is 10⁻³ seconds.
In the question it is given that one nerve impulse begins after one nerve impulse ends.
In 1 second there are 1000 ms.
So, the neuron firing rate would be 1000/second. This means that a nerve impulse will fire a thousand times each second.
