“…Auditory responses to right-ear deviants were enhanced during sad mood as compared to neutral mood, reflecting mood-dependent modulation of mismatch responses to consonant-vowel syllables. Previous studies investigating the effect of emotional context on the processing of neutral auditory stimuli reported enhanced acoustic novelty processing for negative valence [20]–[23]. In a similar vein, dysphoric persons show impaired attention disengagement from negative stimuli [45], [46].…”

“…Several studies have investigated the effects of emotional context on pre-attentive processing of auditory stimuli with electrophysiological measures [20]–[22]. Alexandrov and colleagues [20] created an emotional context by monetary reward or punishment and reported significantly larger auditory cortex event-related potentials in response to negative as compared to positive trials.…”

In an fMRI study by Domínguez-Borràs and colleagues [23], subjects conducted a color decision task embedded in the presentation of facial expressions of negative and neutral valence.…”

Mood Modulates Auditory Laterality of Hemodynamic Mismatch Responses during Dichotic Listening

Hemodynamic mismatch responses can be elicited by deviant stimuli in a sequence of standard stimuli even during cognitive demanding tasks. Emotional context is known to modulate lateralized processing. Right-hemispheric negative emotion processing may bias attention to the right and enhance processing of right-ear stimuli. The present study examined the influence of induced mood on lateralized pre-attentive auditory processing of dichotic stimuli using functional magnetic resonance imaging (fMRI). Faces expressing emotions (sad/happy/neutral) were presented in a blocked design while a dichotic oddball sequence with consonant-vowel (CV) syllables in an event-related design was simultaneously administered. Twenty healthy participants were instructed to feel the emotion perceived on the images and to ignore the syllables. Deviant sounds reliably activated bilateral auditory cortices and confirmed attention effects by modulation of visual activity. Sad mood induction activated visual, limbic and right prefrontal areas. A lateralization effect of emotion-attention interaction was reflected in a stronger response to right-ear deviants in the right auditory cortex during sad mood. This imbalance of resources may be a neurophysiological correlate of laterality in sad mood and depression. Conceivably, the compensatory right-hemispheric enhancement of resources elicits increased ipsilateral processing.

“…If the stimulus presentation situation is uncertain, the N100 responses are intermediate compared to those elicited in negative and positive situations. This is expected to reflect more thorough processing of negative affective states during the early sensory-specific processing and thus activation of larger amount of neurons in the auditory cortex Developmental Psychobiology (Alexandrov, Klucharev, & Sams, 2007). In the present study the emotional state of the controls can be assumed to be neutral whereas the puerperium mothers were in the state of heightened emotionality (Corter & Fleming, 1990), including both positive and negative affects.…”

The present study evaluated the impact of stimulus type and early motherhood on attentional processing. Auditory ERPs were recorded with a modified novelty oddball paradigm both in mothers who had recently given birth and in control women who were not in the state of early motherhood. Conventional tone pips were used as standards and deviants, and an infant cry served as an experimental stimulus of novelty value. Differences were revealed in the N100 amplitudes between the study groups with higher amplitudes in the mothers. A few days after childbirth the mothers seemed to be in a stage with an increased level of alertness and different types of surrounding stimuli may elicit a stronger arousal response than normally, not just those directly related to the new baby. The gating and the mechanisms of further processing of stimulus information were not different in mothers from controls and seemed to guarantee normal control of stimulus-elicited cognitive load in early motherhood.

“…In an EEG-experiment (Alexandrov et al, 2007) emotional context (monetary reward or punishment) led to significantly larger auditory cortex event-related potentials in response to negative as compared to positive trials. Visually induced emotional states with positive or negative pictures have also been reported to modulate event-related potentials of auditory stimuli (Surakka et al, 1998; Yamashita et al, 2005; Sugimoto et al, 2007; Domínguez-Borràs et al, 2009; Wang et al, 2009).…”

Salient exogenous stimuli modulate attentional processes and lead to attention shifts–even across modalities and at a pre-attentive level. Stimulus properties such as hemispheric laterality and emotional valence influence processing, but their specific interaction in audio-visual attention paradigms remains ambiguous. We conducted an fMRI experiment to investigate the interaction of supramodal spatial congruency, emotional salience, and stimulus presentation side on neural processes of attention modulation. Emotionally neutral auditory deviants were presented in a dichotic listening oddball design. Simultaneously, visual target stimuli (schematic faces) were presented, which displayed either a negative or a positive emotion. These targets were presented in the left or in the right visual field and were either spatially congruent (valid) or incongruent (invalid) with the concurrent deviant auditory stimuli. According to our expectation we observed that deviant stimuli serve as attention-directing cues for visual target stimuli. Region-of-interest (ROI) analyses suggested differential effects of stimulus valence and spatial presentation on the hemodynamic response in bilateral auditory cortices. These results underline the importance of valence and presentation side for attention guidance by deviant sound events and may hint at a hemispheric specialization for valence and attention processing.
