These videos provide an overview of the Nengo 1.4 interface and basic examples of how to use Nengo 1.4.
These videos capture the execution of the demo scripts included with Nengo 1.4. They explain what the demo is intended to show.
Basal ganglia based simulations
These videos show various example models running in Nengo 1.4. Many are in the model archive.
