Table 1.
(A) Anticipatory fear processing in anticipation of the presentation of spider pictures: ASL presymptom provocation task Session 1 versus ASL presymptom provocation task Session 2. (B) Fear post event processing after the presentation of spider pictures: ASL postsymptom provocation task Session 1 versus ASL postsymptom provocation task Session 2. The first three columns describe the clusters resulting from the t‐contrast comparing mean CBF images. The last three columns show the quantified CBF values and the result of the T‐test comparing the mean CBF values
