Teaching bioelectricity and neurophysiology to medical students using LabAXON simulations

Area of Science:

• Neuroscience
• Medical Education

Background:

• Traditional patch-clamp electrophysiology is equipment-intensive and difficult to scale for large medical student cohorts.
• Neurophysiology education often relies on lectures, limiting hands-on experience with concepts like membrane potential and ion channel dynamics.

Purpose of the Study:

• To present an in silico practical activity for teaching neurophysiology to large groups of medical students.
• To demonstrate key neurophysiological concepts, including action potentials and ion channel function, using simulation software.

Main Methods:

• Utilized LabAXON simulation software for an in silico neurophysiology practical.
• Included activities on action potential parameters, Nernst potentials, stimulus threshold, refractory period, and voltage-clamp experiments.
• Emphasized quantitative measurements, correct unit usage, and adaptable difficulty levels.

Main Results:

• The in silico activity successfully demonstrated neuronal action potential parameters and ion channel behavior.
• Students could perform quantitative measurements related to Na+ and K+ channels and action potential characteristics.
• The activity was adaptable for various class sizes and online delivery, receiving positive student feedback on consolidating lecture material.

Conclusions:

• In silico simulation offers an effective, scalable alternative to traditional methods for neurophysiology education.
• The LabAXON-based practical enhances student comprehension of fundamental neurophysiological principles.
• This approach is suitable for diverse learning environments, including large classes and online platforms.
