(A) Time series of mean \(\Phi _{\mathrm {MIP}}\) for both conditions (blue: SYNC, red: ASYNC). The stimulus phase covers \(300{-}600\) s. The other regions indicate resting states (no stimulus). The computational time frame for IIT is 250 (2 s). A moving-average (sample length 150 steps) was calculated in the time series to make temporal changes of values easy to see (Niigata) \(\Phi _{\mathrm {MIP}}\) of SYNC and ASYNC values drops significantly compared with each rest state (\(*p < 0.05\), \(**p < 0.01\), \(***p < 0.005\)).
