About This Simulation
The Action Potential Architect is an advanced interactive educational tool designed to provide a comprehensive understanding of neural signaling. By manipulating key parameters of a neuron, such as axon diameter, myelination, and ion channel densities, users can observe their direct impact on the action potential. This simulation bridges the gap between theoretical neuroscience and practical visualization, making it an invaluable resource for students, educators, and researchers alike.
The tool not only demonstrates the fundamental principles of action potentials but also delves into pathological states and optimization strategies. Whether you're exploring the effects of diseases like Multiple Sclerosis or experimenting with ways to enhance signal speed and energy efficiency, this simulation offers a hands-on approach to learning.
How to Use
- Adjust Parameters: Use the sliders in the "Neuron Parameters" panel to modify the axon's diameter, myelination level, and the density of sodium (Na+) and potassium (K+) ion channels. Observe how these changes affect the neuron's behavior in real-time.
- Stimulate: Click the "Stimulate" button to fire an action potential with your current settings. The results will be displayed on the graph, showing the voltage changes over time.
- Scenarios: Explore pre-configured setups like a "Dysfunctional" neuron or a model for "Multiple Sclerosis" to understand pathological states. Each scenario provides a unique perspective on neural dynamics.
- Challenges: Test your knowledge and problem-solving skills by selecting a challenge. Adjust the parameters to meet specific goals, such as fixing a non-firing neuron, maximizing signal speed, or conserving energy.
- Analyze Metrics: After each simulation, review the metrics below the graph to quantify the neuron's performance. Key metrics include conduction velocity, peak voltage, signal fidelity, and energy cost.
- Interactive Demo: Use the "Play Demo" button to see an automated demonstration of parameter adjustments and scenario cycling. This feature is perfect for presentations or gaining a quick overview of the simulation's capabilities.
- Accessibility: The tool supports mouse, touch, and keyboard controls, ensuring full accessibility for all users.
