The current pilot study was designed to investigate mechanisms of suppression of emotional and non-emotional words with Anderson's Think/No-Think paradigm using functional near-infrared spectroscopy (fNIRS). We found no differences in the suppression of negative, positive and neutral words on the behavioral level. Neurophysiological data, however, have(More)
Randomness of functional Magnetic Resonance Imaging (fMRI) resting-state time-series has recently been used as a biomarker for numerous disorders including Alzheimer's and Parkinson's disease as well as autism. To date, however, it remains unknown whether and to what degree personality traits are associated with the randomness of resting-state temporal(More)
Impulsivity is a trait shared by many psychiatric disorders and therefore a suitable intermediate phenotype for their underlying biological mechanisms. One of the molecular determinants involved is the NOS1 ex1f-VNTR, whose short variants are associated with a variety of impulsive behaviors. Fifty-six healthy controls were stratified into homozygous long(More)
Nitric oxide (NO) synthase produces NO, which serves as first and second messenger in neurons, where the protein is encoded by the NOS1 gene. A functional variable number of tandem repeats (VNTR) polymorphism in the promoter region of the alternative first exon 1f of NOS1 is associated with various functions of human behavior, for example increased(More)
The present study explored the neurophysiological correlates of perception and recognition of emotional facial expressions in adolescent anorexia nervosa (AN) patients using event-related potentials (ERPs). We included 20 adolescent girls with AN and 24 healthy girls and recorded ERPs during a passive viewing task and three active tasks requiring processing(More)
Smoking is among the leading causes of mortality worldwide. Discontinuing smoking can increase life expectancy to the presmoking level. Unaided attempts are often ineffective, strengthening the necessity of cognitive-behavioral therapy (CBT), nicotine replacement or pharmacotherapy. Still, relapse rates are high. Recently, a modulation of nicotine craving,(More)
