BACKGROUND Structural and Electroencephalography (EEG) abnormalities in right temporoparietal cortex have been associated with family history of depression (FH). Here we investigate if functional abnormalities in this area, indexed by attenuated responses to emotionally arousing stimuli, are also family-history-dependent. METHODS Neuromagnetic activity(More)
To perceive a coherent environment, incomplete or overlapping visual forms must be integrated into meaningful coherent percepts, a process referred to as "Gestalt" formation or perceptual completion. Increasing evidence suggests that this process engages oscillatory neuronal activity in a distributed neuronal assembly. A separate line of evidence suggests(More)
Animal models and human functional imaging data implicate the dopamine system in mediating enhanced encoding of novel stimuli into human memory. A separate line of investigation suggests an association between a functional polymorphism in the promoter region for the human dopamine 4 receptor gene (DRD4) and sensitivity to novelty. We demonstrate, in two(More)
