MEG responses to Stim-1 and Stim-2. Grand averaged Areal Mean (AM) waveforms (N = 9) in the (A) left hemisphere and (B) right hemisphere. Left panel: orange line indicates the upright scrambled two-agent BM (Stim-1) and the green line indicates the inverted scrambled two-agent BM (Stim-1). Right panel: blue line indicates the Up-Interacting condition, red line indicates the Up-Swapped condition, aqua line indicates the Inv-Interacting condition, and pink line indicates the Inv-Swapped condition. We computed areal means across 20 gradiometer pairs in left and right occipitotemporal regions, respectively (the location of selected sensors is shown in the left upper panel of each graph). While a neuromagnetic response was observed at 250 – 270 ms on average in Stim-1, a neuromagnetic response was observed at 340 ms on average in Stim-2. The shaded area in the background depicts the standard error of the mean (S.E.M.).
