How do I simulate a neuron firing?

Open this page and use the live Phylogenetic Distance tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a neuron firing from your own measurements.

Observed differences

The more two DNA sequences differ, the longer ago they shared an ancestor. But raw differences undercount, because a site can mutate more than once. The Jukes–Cantor correction inflates the raw distance to estimate the true number of substitutions per site. Educational tool.

Governing equation

d = - \frac{3}{4} ln (1 - \frac{4}{3} \cdot 0.150) = 0.167 subs/site

Reading this result: About 15.0% of sites differ, and the Jukes–Cantor correction inflates that to 0.167 substitutions per site to account for hidden multiple hits.

About this simulation

The full Phylogenetic Distance tool models a neuron firing with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
