Modifying Global Coupling (G) in Reduced Wong-Wang model with excitation and inhibtion

[Justin Wang]

Hello,

Happy holidays!

I am trying to work with DecoBalancedExcInh (code here https://github.com/the-virtual-brain/tvb-root/blob/master/tvb_library/tvb/simulator/models/wong_wang_exc_inh.py). 

There is an option to configure G, global coupling, in the model attributes - e.g. model=DecoBalancedExcInh(G=3.8)

There is also the option to configure G when setting up the Simulator coupling - e.g. coupling=coupling.Linear(a=numpy.array([3.8]))

Before I start digging through the code/testing various configurations, would anyone happen to know off the top of their heads how these G settings interact? Does one override the other or do they combine (multiplicatively?).

Thank you very much!

Justin

hi

They combine multiplicatively; set one to 1.0 and tune the other.  Both are available for flexibility.

cheers,

Marmaduke
