Neurons, membranes, proteins — the machinery of life, visualised
Neuroscience and biophysics simulations bring the molecular and cellular machinery of life into interactive focus. From the cascading ion channels of a cardiac action potential to the folding pathways of a protein chain, these models let you manipulate parameters and observe emergent biological behaviour in real time.
The neural network visualiser implements full backpropagation learning — watch weights adjust as the network learns to classify data. The FitzHugh-Nagumo model captures the excitable membrane dynamics that underpin every heartbeat and nerve impulse, while membrane diffusion demonstrates how passive, facilitated, and active transport maintain cellular homeostasis.
These simulations connect abstract equations to tangible biology. The same Navier-Stokes simplifications used in the blood flow model inform real medical device design, and Monte Carlo methods for protein folding drive modern drug discovery pipelines. Running them in a browser makes computational biophysics accessible without specialised software.

Every interactive Neuroscience model on this page runs instantly in your browser with no downloads or accounts — from spiking neural networks and Hodgkin-Huxley action potentials to synaptic transmission, brainwave oscillations and blood flow. Each Neuroscience simulation lets you adjust parameters and watch the biophysics respond in real time, making it easy to learn Neuroscience online whether you are a student revising for exams, an educator demonstrating concepts in class, or a curious mind exploring how the brain works. The same computational methods power real-world applications such as designing brain-computer interfaces, modelling drug interactions and planning vascular surgery.
