Clarifying the role of the rostral dmPFC/dACC in fear/anxiety: learning, appraisal or expression?

Further confirming the visual impression, planned post-hoc one-tailed t-tests on CS+>CS− difference scores showed no significant activation during early conditioning [UF-Cond1: t(16) = 0.28, p = 0.393], an already significant, though rather weak, reaction during late conditioning [UF-Cond2: t(16) = 2.11, p = 0.025] and a strong and highly significant reaction to the CS+ during testing [UF-Test: t(16) = 3.81, p = 0.001].
