Jansen-Rit - sanity check

[Daniel Polyakov]

Hi,

I'm having hard time generating simple alpha 10Hz oscillations with Jansen-Rit model on TVB. 

I've tried this tutorial example, using data[:,1,:,0] - data[:,2,:,0] as the output:

https://nbviewer.thevirtualbrain.org/url/docs.thevirtualbrain.org/demos/simulate_region_jansen_rit.ipynb

but the produced oscillations are around 4Hz.

This code produces oscillations around 8Hz:

https://gist.github.com/maedoc/d6780270b47f956c541eef5ed85e8194#file-jr95-py

but it's not the basic Jansen-Rit model.

Does anyone have a working code example he can share?

Thanks in advance,

Daniel

Hi Daniel, 

I'm having the same issue, producing 4Hz oscillations. 

Were you able to solve this? 

Thanks,
