Space-time dynamics of NEX and NINH to a visual scene with bar moving up from the CFOV. Non-statistically significant cortex is light blue. Statistically significant NINH dark blue to black scale (FDR at 0.05); statistically significant NEX colors from green to red (FDR at 0.05). Maximum scale values 5 10−6. The time after the stimulus start is shown in ms on top and below. Space-time dynamics associated with scene in which a bar moves upwards from the CFOV in animal 2. Non-significant parts, amplitudes from −5 10−7 to 5 10−7. The sequence of events: The NEX appears and spreads in all directions into the adjacent cortex from the two CFOV mapping sites (8/8). Then an offshoot of the NEX in 19/21 moves toward area 17/18 (7/7) and the NEX at 17/18 moves left (8/8). The NEX reached its maximal amplitude in areas 17/18 (7/8) and in areas 19/21 (5/7). The NEX diminishes and the NINH took over almost simultaneously in areas 17/18 and 19/21 (7/7). The NINH spreads in all directions gaining amplitude (7/7) into all exposed areas (7/8). The NINH shrinks and moves pursuing the earlier NEX in both areas 17/18 (7/8) and areas 19/21 (6/6).
