Active probing to highlight approaching transitions to ictal states in coupled neural mass models
Fig 1
(a) Representation of each coupled neuronal population and corresponding subpopulations. Excitatory interneurons are implicitly represented as the self-feedback loop from main pyramidal cells (EXCi to itself). Each model settings consists of either (I) unilateral (s2) or (II) simultaneous bilateral low-frequency probing stimulation (s1 and s2), while slowly changing one parameter towards ictal activity–A1, B1 or K.
