Me or you? Neural correlates of moral reasoning in everyday conflict situations in adolescents and adults.

Throughout adolescence, progress in the understanding of the moral domain as well as changes in moral behavior is observable. We tested 16 adolescents (14-16 years of age) and 16 healthy adults (22-31 years of age) on the developmental changes in everyday moral decision making using functional magnetic resonance imaging (fMRI). Using verbal stories describing everyday moral conflict situations, subjects had to decide between a moral standard or a personal desire.

Aversive faces activate pain responsive regions in the brain.

Recent evidence points to an overlap in the neural systems processing pain and social distress. In this functional MRI study we focus on the possible interplay between the processing of a psychosocial stressor and somatic pain within pain responsive brain regions, the latter being identified in an independent localizer experiment. A paradigm based on emotional induction (Hariri et al.

Common and distinct neural networks for false-belief reasoning and inhibitory control.

Ample behavioral evidence has shown that the ability to attribute false beliefs as part of a Theory of Mind (ToM) and the ability to inhibit a prepotent response are strongly correlated in both children and adults. Frequently reported areas associated with both processes are the right temporo-parietal junction (TPJ) and the medial prefrontal cortex (MPFC). Nevertheless, the exact nature of the relationship between belief-reasoning and inhibitory control at the neural level remains unclear.

How should I decide? The neural correlates of everyday moral reasoning.

The present fMRI study is the first that investigates everyday moral conflict situations in which a moral standard clashes with a personal desire. In such situations people have to decide between a morally guided and a hedonistic behaviour. Twelve healthy subjects were presented with verbal stories describing conflicts with either moral or neutral content.

Dissociation of neural correlates of verbal and non-verbal visual working memory with different delays.

Background: Dorsolateral prefrontal cortex (DLPFC), posterior parietal cortex, and regions in the occipital cortex have been identified as neural sites for visual working memory (WM). The exact involvement of the DLPFC in verbal and non-verbal working memory processes, and how these processes depend on the time-span for retention, remains disputed.

Methods: We used functional MRI to explore the neural correlates of the delayed discrimination of Gabor stimuli differing in orientation.

Neural correlates of emotional working memory in patients with mild cognitive impairment.

Emotional stimuli can have beneficial effects on memory in healthy aged subjects and partly on patients with dementia. So far, no experimental study has explored the effects of memory for emotional stimuli in patients with mild cognitive impairment (MCI), a concept that describes a transitional state between normal aging and dementia. The present fMRI study explored working memory for emotional stimuli in 16 patients with amnestic MCI (aMCI) and 16 healthy aged participants.
