Positron emission tomography was used to investigate common versus specific cortical regions for the maintenance of spatial versus phonological information in working memory (WM). Group and single-subject analyses of regional cerebral blood flow during a new 2 x 2 factorial n-back task were performed. Eight subjects had to memorize either phonological(More)
The pathology of Borderline personality disorder (BPD) is poorly understood and its biological basis remains largely unknown. One functional brain imaging study using [(18)F]Deoxyglucose-PET previously reported frontal and prefrontal hypometabolism. We studied brain metabolism at baseline in 12 medication-free female patients with BPD without current(More)
BACKGROUND The large differences in cardiovascular disease rates between Eastern and Western Europe have largely developed over the last few decades, and are only partly explained by classical risk factors. This study was set up to identify other potential determinants of these differences. METHODS This was an ecological study comparing random samples of(More)
Imaging the presynaptic dopamine transporter with cocaine analogues and single-photon emission tomography (SPET) has proven to be a potential diagnostic tool for classifying the extent and degree of dopaminergic nerve cell loss. For correct interpretation of scan results, however, knowledge of the intra-/interobserver variation of data evaluation is(More)
