A neuron just sent a neural impulse.It will be one to two milliseconds before another neural impulse can be generated.What do we call this brief time increment,when another neural impulse cannot occur

A)  resting potential 
B)  absolute refractory period 
C)  postsynaptic discharge 
D)  all-or-none period

This brief time increment, when another neural impulse cannot occur, is called the absolute refractory period. During this period, the neuron is unable to fire another action potential, regardless of the intensity or strength of the incoming stimuli. This is due to the fact that the ion channels in the membrane are in a state of inactivation and need to be reset to allow for another action potential to occur. The absolute refractory period typically lasts for about one to two milliseconds.
