Abstract excerpt

The affect-modulated acoustic startle response (ASR) might be a promising indicator for emotional reactivity as an endophenotype (an intermediate level between genetics and phenotypes), which we expected to be associated with the DRD4 polymorphism. Therefore, the affect-modulated ASR was examined in 114 healthy volunteers, 74 lacking the DRD4 7R allele (7R-absent group) and 41 with at least one DRD4 7R allele (7R...
