Simulation lab
Models you can run, change and share. Each says what it includes and what it leaves out, shows where every number comes from, and is checked on the validation page.
Simplified model Teaching models for learning. Not for diagnosis, prognosis or treatment planning.
- Lab 1Neuron labFire a Hodgkin-Huxley membrane, strip a neuron to one equation, and time a spike along an axon.membraneaxon
- Lab 2Signal journeyTime a command from cortex to muscle, a knee jerk, or a touch to the brain, on a 3D body.timingbody
- Lab 3Lesion explorerCut part of the cord and see which pathways lose their signal below the cut, on each side.pathwaysinjury
- Lab 4Alignment and loadTilt the trunk, hold a weight and see the load on a lumbar disc in a simple lever model.mechanics
- Lab 5Decode movement intentSimulate motor cortex neurons and decode a cursor’s direction from their firing.brain-computer interface
- Lab 6The digital bridgeHow a brain-spine interface links decoded intent to spinal stimulation, step by step.frontier
- Lab 7Walking rhythmTwo mutually inhibiting neurons make an alternating rhythm, like left and right legs.spinal circuits
- ChecksModel validationEvery model compared with a published result, an exact answer or a property it must have.
