Cortical stimulation lab

Explore how electrode geometry, current steering and neural anatomy shape electrical recruitment.

A tissue-scale experiment,
one neuron at a time.

Run an experiment to calculate neural responses. Each bright soma will be a solved cell, surrounded by the anatomical population at its physical scale.

Mechanistic exploration: finite current sources in uniform tissue and idealized active neurons. Bright cells are the solved sample; dim cells have no assigned activation result. Read the model’s scope.
