 # ### Simulate the network
 # Now that we have the neurons and the graph, we can simulate the network. We use the `system_from_graph` function to create a system of ODEs from the graph and then solve it using the DifferentialEquations.jl package, but for performance scaling reasons we will use the experimental option `graphdynamics=true` which uses a separate compilation backend called [GraphDynamics.jl](https://github.com/Neuroblox/GraphDynamics.jl). The GraphDynamics.jl backend is still experimental, and may not yet support all of the standard Neuroblox features, such as those seen in the Spectral DCM tutorial.
