Neural Activity Visualization
Explore real-time 3D visualization of neural membrane voltage dynamics. Action potentials propagate through dendritic branches and axonal projections, creating complex patterns of electrical activity. Now, you can select from multiple neuron types—including Pyramidal, Interneuron, and Purkinje cells—using the new Neuron Type selector in the controls panel. The simulation provides full control over playback speed, timeline scrubbing, and visual effects, including options to toggle glow effects and axon differentiation for different viewing experiences. Rendering is optimized for real-time performance, with smooth animations and responsive interactions. The neuron morphologies are biologically inspired, and voltage propagation follows biophysical principles with distance-based delays. Interact with the simulation using mouse, touch, or keyboard controls to rotate and zoom the 3D neuron model.
How to Interact
Interact with the simulation in several ways:
- Neuron Type: Use the selector to instantly switch between Pyramidal, Interneuron, and Purkinje morphologies.
- Rotate: Click and drag with your mouse, or use arrow keys.
- Zoom: Scroll with your mouse wheel, use +/- keys, or pinch on touch devices.
- Timeline & Speed: Scrub through the timeline or adjust animation speed with the sliders.
- Visual Effects: Toggle glow and axon differentiation for different viewing experiences.
Technical Features
This enhanced version of the simulator features a modern, responsive user interface with glassmorphism effects and smooth animations. Real-time statistics are displayed, including frame rate, voltage levels, and the number of active segments. Advanced controls allow you to adjust animation speed, toggle visual effects, reset the simulation, and now select neuron type. Rendering improvements provide better color schemes, axon differentiation, and optimized performance. The layout is mobile-optimized and works seamlessly on all devices.
Future Directions
