Sensitivity analysis enlightens effects of connectivity in a Neural Mass Model under Control-Target mode

Response as BOLD signals in E-E and E-I connectivities.
Left: E-E connectivity, right E-I connectivity. (A, B) A stimulation of 0.1 nA is applied upon the excitatory pool of the Control area during 20 s. (C, D) Time course of stimulations are made typical of a TNT task with stimulation steps during 3 s, separated by random intervals between 2.4 and 3.6 s. See comments in Sec 3.4.1.
