The code provided is a simulation of a computational model that represents neuronal dynamics, focusing on the electrical activities within a neuron. Here is an overview of the biological basis of the components present in the code:

Membrane Potential

The code models the neuronal membrane potential (Vm), which is the electrical potential difference across the neuron's membrane. This is fundamental to understanding how neurons transmit signals.

Ionic Currents

The model includes calculations for various ionic currents vital for neuronal function:

Gating Variables

Ion Concentrations

The model tracks various intra- and extracellular ion concentrations:

Ion Pumps

Nernst Potentials

The Nernst potentials for sodium, potassium, and chloride are calculated to represent the equilibrium potential for these ions, which is crucial for determining ionic movement directions across the membrane.

Anoxia Simulation

Overall, this code aims to model the electrophysiological behaviors of neurons by incorporating ionic currents, concentration dynamics, and the effects of anoxia, thereby providing insights into how neurons maintain and propagate electrical signals under varying physiological conditions.
