Final answer:
The time period when another neural impulse cannot occur immediately after one has been sent in a neuron is known as the refractory period.
Step-by-step explanation:
The brief time period after a neural impulse has been sent, during which another neural impulse cannot be generated, is called the refractory period. This period ensures that each action potential is a separate, all-or-none event and allows the neuron to reset before the next action potential. There are two phases within the refractory period: the absolute refractory period, during which no new action potential can be initiated, and the relative refractory period, during which a new action impulse can be started but only with a stronger stimulus.
The brief time period after a neural impulse when another neural impulse cannot be generated is called the refractory period.
During the refractory period, the cell membrane of a neuron is unable to generate another action potential. This period allows the voltage-sensitive ion channels to return to their resting configurations.
After this refractory period, a new action potential could be started, but only by a stronger stimulus than the one that initiated the previous action potential.
