Background:

• Neural networks are crucial in diverse scientific fields, including medicine, engineering, and pharmacology.
• Understanding single neuron function is key to deciphering complex brain operations and neural network behavior.
• Mathematical models simulating neuronal information transmission are vital tools for neuroscientists.

Approach:

• This review critically examines four prominent single-compartment mathematical neuron models: Hodgkin-Huxley, Izhikevich, Leaky Integrate-and-Fire, and Morris-Lecar.
• A comparative analysis is presented, focusing on biological plausibility, computational complexity, and diverse applications.
• The evaluation is based on current scientific literature and modern research findings.

Key Points:

• The Hodgkin-Huxley model offers high biological detail but is computationally intensive.
