What would happen if nerves didn't have refractory period? And, what part of his nervous system or neurons are not needed?

  • $\begingroup$ Who is "his"? Are you talking about a human neurologic system in general? $\endgroup$ – Vance L Albaugh May 27 '16 at 18:59
  • $\begingroup$ Yes it is a scenario case. $\endgroup$ – Milena May 27 '16 at 19:10

  • $\begingroup$ Are you asking about the theoretical implication in terms of the function of neural system? Clearly this is not a biophysically plausible scenario since it will allow infinite number of action potentials in a finite time. $\endgroup$ – Memming May 29 '16 at 13:08

Refractory period returns the repolarization period to the nerve's resting potential . it's the time taken for recovery of a neuron to generate another impulse being excited by another stimulus . so if nerve doesn't have refractory period they wouldn't be able to return to its resting potential & generate new impulse . moreover the repolarization potential further exceeds its value and cause hyperpolarization , so its badly necessary to restore to resting potential by expelling na+ and taking k+ in . unless it would be impossible to restore the resting potential & be ready to get excited to transmit another impulse via the electrochemical pathway . one more benefit of refractory period is that it causes unidirectional impulse conduction. I didn't get the 2nd part of your question. What are you trying to mean , make it more clear.
