Detailed explanation-1: -the level of stimulation required to trigger a neural impulse. in neural processing, a brief resting pause that occurs after a neuron has fired; subsequent action potentials cannot occur until the axon returns to its resting state. a neuron’s reaction of either firing (with a full-strength response) or not firing.
Detailed explanation-2: -After the neuron has fired, there is a refractory period in which another action potential is not possible. The refractory period generally lasts one millisecond.
Detailed explanation-3: -During the resting pause following an action potential, called the refractory period, the neuron pumps negatively (positively/negatively) charged ions outside the cell.
Detailed explanation-4: -Neural transmission occurs when a neuron is activated, or fired (sends out an electrical impulse).
Detailed explanation-5: -The nerve impulse caused by a change in the electrical charge across the cell membrane of the axon. When the neuron “fires, ” this charge travels down the axon and causes neurotransmitters to be released by the terminal buttons. The fact that an action potential in the axon occurs either full-blown or not at all.
