2012, Psychiatry Research - NeuroimagingCitation Excerpt :All the above methodological differences did not apparently bias neuroimaging results. The only SPECT study (O'Carroll et al., 1993) obtained results that cannot be compared to those of other studies, as its results do not match those of the other two studies that used 99mTc-exametazime as a tracer to investigate anxiety-related issues (Conca et al., 2000; Lucey et al., 1997, not included here). Other SPECT studies of anxiety disorders used markers of serotonergic or GABAergic activity, while exametazime is used exclusively as a blood perfusion tracer.

2009, Psychiatry Research - NeuroimagingCitation Excerpt :Recently, the lifetime prevalence of specific phobia was reported to be 12.5% in the USA (Kessler et al., 2005). The first wave of neuroimaging studies explored patterns of brain activity during phobic states using symptom provocation designs with visual (Fredrikson et al., 1993, 1995; Wik et al., 1993; Johanson et al., 1998), tactile (Mountz et al., 1989; Rauch et al., 1995) or auditory phobic cues (O'Carroll et al., 1993). The initial hypothesis was that the amygdala would display increased activity during fear provocation based on its established role in vigilance and negative affect (cf. Mountz et al., 1989; Fredrikson et al., 1993; Rauch et al., 1995).
