or the threshold will not be reached and no wave will occur. what is this response to stimulus called?

The all-or-none response in neurons to reaching the threshold for an action potential is referred to as the 'all-or-none principle.' No action potential occurs if the threshold is not reached.

  • The response to stimulus mentioned in the question refers to an action potential, which is an all-or-none response.
  • If the stimulus is strong enough to depolarize the membrane to the threshold level (typically -55 mV), an action potential will be generated, and the voltage will spike up to around +30 mV.
  • If the threshold is not reached, then no action potential occurs and the neuron remains at its resting state.
  • This is known as the all-or-none principle, which is critical for nerve impulse propagation.
  • Stronger stimuli cannot produce a 'larger' action potential but can lead to more frequent action potentials.
