Source estimations for the comparison between the “human sender” and the “computer sender” in the P3 time window (300–450 ms)

Cluster level	Peak level		MNI coordinates (mm)			AAL
No. of significant voxels	Peak t(1,90)	Peak p-uncorrected	x	y	z	Area
807 (725a, 549b)	6.73c	<0.001	−42	−64	−18	Fusiform L
795 (723a, 553b)	6.63c	<0.001	36	−50	−18	Fusiform R
63	3.35	<0.005	−12	−80	−12	Lingual L
81	2.90	<0.005	32	−84	6	Midoccipital R
63	2.77	<0.005	40	−82	10	Midoccipital R

Results show enhanced source activations for the human sender in visual areas. For each significant peak, respective coordinates (x, y, and z) are reported in MNI space. A cluster may exhibit more than one peak, whereas only the largest peak is displayed. Area, Peak-level brain region as identified by the AAL atlas; R/L, laterality right or left.
