Neuron

Step into the microscopic world of a firing neuron with this Java simulation. Neuron lets you control and observe the intricate dance of ions—sodium, potassium, and others—as they flow across the membrane, driving the electrical impulses that underlie all brain function. The program models the stages of an action potential with scientific accuracy. By manipulating variables, users gain an intuitive understanding of threshold potentials, refractory periods, and synaptic transmission. It's a hands-on digital lab for anyone curious about how our cells communicate.
