What is the difference between resting membrane potential and equilibrium potential?

The difference between the membrane potential and the equilibrium potential (-142 mV) represents the net electrochemical force driving Na+ into the cell at resting membrane potential. At rest, however, the permeability of the membrane to Na+ is very low so that only a small amount Na+ leaks into the cell.

What is the equilibrium potential of K+?

Moreover, K+ is a positively charged ion that has an intracellular concentration of 120 mM, an extracellular concentration of 4 mM, and an equilibrium potential of -90 mV; this means that K+ will be in electrochemical equilibrium when the cell is 90 mV lower than the extracellular environment.

What is depolarisation and Repolarisation?

Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels. Repolarization is caused by the closing of sodium ion channels and the opening of potassium ion channels.

What happens depolarization?

During depolarization, the membrane potential rapidly shifts from negative to positive. As the sodium ions rush back into the cell, they add positive charge to the cell interior, and change the membrane potential from negative to positive.

What do you need to know about the metaneuron?

MetaNeuron is a computer program that models the basic electrical properties of neurons and axons. The program is intended for the beginning neuroscience student and requires no prior experience with computer simulations. Different aspects of neuronal behavior are highlighted in the six lessons presented in MetaNeuron.

Who was the creator of the metaneuron computer?

MetaNeuron was created and written by Eric A. Newman and Mark H. Newman. The computer code was written by Mark H. Newman. It was inspired by Jerome Y. Lettvin’s transistor model of the axon, the MetaMembron. Development of MetaNeuron was supported in part by the Neuroscience Department, University of Minnesota.
