Brain areas more activated by fearful than by neutral peripherally presented faces in the three analyzed time windows.

<p>For each activation cluster, the Talairach coordinates correspond to the voxel of maximal intensity obtained after the ERB analyses, the volumes are expressed in cm³. The threshold is set at uncorrected p<0.01 (*p<0.005, **p<.001).</p

Group source analysis.

<p>The student-t statistic 3D map resulting for the group source analysis are thresholded by the corresponding p-value<0.01. During the first 130 ms, not-consciously perceived peripheral fearful faces enhanced the neuronal activity in the right anterior medial temporal lobe, including parahippocampal gyrus and amygdala.</p

Brain areas more activated by fearful than by neutral centrally presented faces in the three analyzed time windows.

<p>For each activation cluster, the Talairach coordinates correspond to the voxel of maximal intensity obtained after the ERB analyses, the volumes are expressed in cm³. The threshold is set at uncorrected p<0.01 (*p<0.005, **p<.001).</p

Sensor responses averaged across subjects and conditions.

<p>Event-related beamformer source analyses were performed in three 50 ms time windows (grey) surrounding the three major peaks. Magnetic activity maps represent the sensor activity for each maximum peak amplitude.</p

Example of trial.

<p>Each trial started with two scrambled faces and a fearful or neutral face presented for 33 ms, centrally or peripherally, immediately masked by 3 neutral faces. After a variable delay the target stimulus was appearing. The subject was asked to press a button when a happy face was occurring.</p

Time courses of activities at the right amygdala site.

<p>The activity elicited at the right amygdale site (21, −4, −15) by peripherally presented stimuli is depicted in black for fearful faces, in grey for neutral faces. The first peak appearing around 115 ms is stronger for fearful faces. The reported pseudo-Z values are taken from the subtraction of time course activities related to fearful faces minus those related to neutral faces in the corresponding voxels.</p

Description of a trial: A fixation stimulus (a house picture) centrally presented for 600 ms, is followed by the target stimulus presented for 140 ms.

<p>The fixation stimulus is then presented until the subject's response.</p
