From neural networks to membrane transport — explore the biophysics of cells, neurons, and physiological systems interactively.

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.
