the models in TVB have a notion of variables of interest, to avoid keep too much data in memory for long simulations with large models. For JR, this is the first four state variables,
which you can change when you instantiate the model.
I'm a bit unsure about something and could use some clarification. My goal is to obtain simulated EEG signals specifically generated for stimuli. The code mentioned in the previous email simulates EEG signals using the Jansen-Rit model, which involves four states. While I understand that, on a regional level, there are typically four states due for generating temporal averaging, I'm aware that EEG signals themselves do not inherently have four states.
I'm seeking resources that can help me understand the simulation process and how the forward model is utilized to generate EEG signals. I feel a bit confused and would like to find a way to simulate EEG signals that are responsive to stimuli, allowing me to perform Event-Related Potentials (ERPs) analysis. If you have any guidance on obtaining simulated ERPs for a given stimulus, I would greatly appreciate it.
