Tutorial

This simulation demonstrates how intracortical electrode arrays record neural activity and how it can be decoded into intended movement direction and magnitude using simple linear models.

1. Enter simulated neuron firing rates (in Hz) — one per line.
2. Select a decoding algorithm: Wiener Filter or Linear Regression.
3. Click “Decode Movement” to estimate the intended movement vector.
4. The canvas displays the predicted 2D movement intention.
5. You can then download the results and visualization as a PDF.

About This Tool

This decoder illustrates the transformation from neural signals to movement intention — a core principle in brain-computer interface research. The tool uses a linear mapping between simulated neuron firing rates and a 2D movement output space, similar to early BCI decoding paradigms.

Applications include motor prosthetics, assistive technology, and neuroscience education.
