Is functional amygdala-hippocampus connectivity during anticipation of aversive events associated with Gray 's trait `` sensitivity to punishment ''?
In summary, we show that individual differences regarding Gray's trait sensitivity to aversive events as defined by the reinforcement sensitivity theory are associated with the neural dynamics of the amygdala-hippocampal circuit during anticipation of aversive events. In particular, evidence is provided for a relationship between functional brain imaging data and a psychometric approach specifically measuring Gray's trait sensitivity to aversive events, thereby potentially identifying the neural substrate of the behavioral inhibition system.
This study suggests that in follicular lesions of the thyroid, a benign FNA biopsy report from an experienced cytopathologist has a high positive predictive value. The predictive value may not, however, be high enough to preclude surgery; other factors may need to be considered before recommending a nonoperative approach.
