Some Books are showing the resting potential of neurons as -65mV

Eg : NEUROSCIENCE-EXPLORING THE BRAIN,Fourth Edition,2016,Wolters Kluwer

enter image description here

while Majority of internet sites(including Wikipedia) are showing it as -70mV

Which one is the correct value,Why is there a small difference ?

  • $\begingroup$ This seems a rather specialized question. Why are you concerned about what you admit is a small difference? Does it have any practical relevence to your work? We would be interested to know. $\endgroup$ – David May 3 at 12:45
  • $\begingroup$ @David I was just reading about the resting potential of the neurons in the book mentioned above.The book uses -65mV in all the pages ,when i checked the internet ,it is -70mV everywhere.So i was curious. $\endgroup$ – Rahul.In May 4 at 14:50

Neither is incorrect. Neuronal resting potential is a function of the internal and external concentrations of ions and the conductance of the membrane to those ions via ion channels. Different neurons exhibit a range of resting potentials.

You can calculate the resting potential for a given cell using the Goldman Equation.
