Overall Purpose

The model encapsulates the classic Hodgkin-Huxley type dynamics generalized for specific sodium channels dictated by the parameters and functions used. These dynamics are critical for understanding how neurons respond to stimuli by modeling the ionic mechanisms that lead to action potential initiation and propagation, central to neuronal communication and processing in the brain.

This model is part of a broader effort to simulate neuronal activity computationally, helping to shed light on various neurological processes and conditions through virtual experiments.
