Fig 2. ERPs on the six regions illustrating the effects of IFVs, TVs, and UVs in the three time windows of interest.

Distinct responses to IFV appear in an early window of 200–250 ms and were rightward as seen changing amplitudes at RFC, and also appeared in a late window of 500–650 ms where prolonged shifts appear in parietal sites at MPC and LCP and in frontal sites at RFC. For TVs and UVs, contrasting responses were found in a mid-late window of 300 to 350 ms, as seen in the differential responses at MFC and LFC.
