Effective orienting of attention towards novel events is crucial for survival, particularly if they occur in a dangerous situation. This is why stimuli with emotional value are more efficient in capturing attention than neutral stimuli, and why the processing of unexpected novel stimuli is enhanced under a negative emotional context. Here we measured the(More)
Viewing emotionally negative pictures has been proposed to attenuate brain responses towards sudden auditory events, as more attentional resources are allocated to the affective visual stimuli. However, peripheral reflexes have been shown intensified. These observations have raised the question of whether an emotional context actually facilitates or(More)
Visualizing emotionally loaded pictures intensifies peripheral reflexes toward sudden auditory stimuli, suggesting that the emotional context may potentiate responses elicited by novel events in the acoustic environment. However, psychophysiological results have reported that attentional resources available to sounds become depleted, as attention allocation(More)
Gender differences in brain activity while processing emotional stimuli have been demonstrated by neuroimaging and electrophysiological studies. However, the possible differential effects of emotion on attentional mechanisms between women and men are less understood. The present study aims to elucidate any gender differences in the modulation of unexpected(More)
We used an auditory-visual distraction task to investigate the functional relationship between distraction elicited by auditory novel events and a context of negative emotional processing, both at behavioural and electrophysiological (event-related brain potentials) levels in humans. Participants performed a decision task on pictures disclosing sceneries(More)
Emotionally negative stimuli boost perceptual processes. There is little known, however, about the timing of this modulation. The present study aims at elucidating the phasic effects of, emotional processing on auditory processing within subsequent time-windows of visual emotional, processing in humans. We recorded the electroencephalogram (EEG) while(More)
Unilateral spatial neglect is a neurological disorder characterized by impaired orienting of attention to stimuli located in the contralesional space, typically following right-hemisphere damage. Neuropsychological investigations in the past two decades have demonstrated that neglect is caused by deficits affecting a widespread cortico-subcortical(More)
The dopaminergic (DA) system has been recently related the emotional modulation of cognitive processes. Moreover, patients with midbrain DA depletion, such as Parkinson's Disease (PD), have shown diminished reactivity during unpleasant events. Here, we examined the role of DA in the enhancement of novelty processing during negative emotion. Forty healthy(More)
A recent functional magnetic resonance imaging (fMRI) study by our group demonstrated that dynamic emotional faces are more accurately recognized and evoked more widespread patterns of hemodynamic brain responses than static emotional faces. Based on this experimental design, the present study aimed at investigating the spatio-temporal processing of static(More)
Patients with parietal lesions and unilateral spatial neglect (USN) are unable to detect or respond to information in the contralesional side of space. However, some residual sensory processing may still occur and overcome inattention symptoms when contralesional stimuli are perceptually or biologically salient, as shown for emotional faces or voices.
