“…This is suggested by our observation that we did not observe any DMPFC activation during the preceding expectancy period. This is further supported by analogous findings in recent studies who also observed DMPFC involvement only during attention to pictures but not in the preceding period [Bermpohl et al, 2006a,b] as well as by studies on simultaneous attention [Fichtenholtz et al, 2004;Keightley et al, 2003;Lane et al, 1999;Liberzon et al, 2000;Pessoa et al, 2002;Winston et al, 2003]. This suggests that the DMPFC is specifically involved in attending stimulus perception and its associated mental states rather than being recruited by attention, i.e., expectancy, itself.…”

“…Phan et al [2002] therefore conclude that the DMPFC is engaged in implicit cognitive aspects of emotion processing that are common across emotional tasks. Recent results indicate that this implicit cognitive function may be the specific attentional modulation of emotional stimulus processing [Bermpohl et al, 2006a;Fichtenholtz et al, 2004;Keightley et al, 2003;Lane et al, 1999;Liberzon et al, 2000;Nitschke et al, 2006;Pessoa et al, 2002;Ueda et al, 2003;Winston et al, 2003]. This suggests that neural activity in the DMPFC is characterized by a specific process within a particular domain.…”

Abstract:The dorsomedial prefrontal cortex (DMPFC) has been shown to be involved in attending different states, all including a strong emotional component. It remains unclear, though, whether neural activity in the DMPFC is predominantly determined by either a particular domain, as emotional stimuli, or by a specific process, as attention. Here, we used functional magnetic resonance imaging to test the alternative hypotheses of domain-versus process-specificity in DMPFC. Subjects had to perceive pictures from three different domains, sexual, emotional, and neutral stimuli, in both a nonattended, i.e., unexpected, and attended, i.e., expected mode. Our results show DMPFC activation during attended, i.e., expected stimulus perception when compared with nonattended, i.e., unexpected stimuli perception. DMPFC activation and corresponding behavioral changes (reaction time, subjective ratings) were observed in all three domains, sexual, emotional, and neutral stimuli. As opposed to those process-specific effects that were found predominantly in posterior DMPFC, a process by domain interaction was found to be characteristic for more anterior parts of the DMPFC. Taken together, our findings favour the hypothesis that neural activity in the posterior DMPFC is determined by a specific process, i.e., attending stimuli, and thus characterized by process-specificity rather than by a particular domain, i.e., sexual, emotional, or neutral stimuli, reflecting domain-specificity. This suggests that the anterior and posterior DMPFC is involved in the process of attending mental states while remaining more (posterior DMPFC) or less (anterior DMPFC) independent of the type or domain of the respective stimulus.

“…First, we did not have specific network hypotheses regarding the causal implication of the dorsal stream in the type of emotional modulation under study. Second, it appears that modulation of the dorsal stream by emotional competence is weak (Fichtenholtz et al, 2004). Accordingly, we did not find strong evidence of modulation of activity by the emotional competence of the stimuli in high-order areas associated with the dorsal visual stream using distributed source reconstruction.…”

Visual attention can be driven by the affective significance of visual stimuli before full-fledged processing of the stimuli. Two kinds of models have been proposed to explain this phenomenon: models involving sequential processing along the ventral visual stream, with secondary feedback from emotion-related structures ("two-stage models"); and models including additional short-cut pathways directly reaching the emotion-related structures ("two-pathway models"). We tested which type of model would best predict real magnetoencephalographic responses in subjects presented with arousing visual stimuli, using realistic models of large-scale cerebral architecture and neural biophysics. The results strongly support a "two-pathway" hypothesis. Both standard models including the retinotectal pathway and nonstandard models including cortical-cortical long-range fasciculi appear plausible.

“…From an evolutionary standpoint, organisms benefit from having a mechanism by which highly arousing stimuli can capture attention (Öhman and Mineka, 2001). Indeed, studies that employ emotional stimuli often show an interaction between attention and emotion in the dACC (Carlsson et al, 2004;Fichtenholtz et al, 2004) and experimental tasks that explicitly manipulate attention towards emotion robustly engage the dACC (Hutcherson et al, 2005;Lane et al, 1997a;Taylor et al, 2003).…”

Association between trait emotional awareness and dorsal anterior cingulate activity during emotion is arousal-dependent

et al. 2008

The dorsal anterior cingulate cortex (dACC) is commonly thought to subserve primarily cognitive functions, but has been strongly implicated in the allocation of attention to emotional information. In a previous positron emission tomography (PET) study, we observed that women with higher emotional awareness as measured by the Levels of Emotional Awareness Scale (LEAS) showed greater changes in regional cerebral blood flow (rCBF) in dACC induced by emotional films and recall. In the current study, we tested whether these effects were due to the processing of any nonneutral stimulus, or were specific to conditions of high emotional arousal. Our results extend the previous finding by demonstrating a positive correlation between emotional awareness and dACC activity only in the context of viewing highly arousing pictures. No such relationship was observed when comparing pleasant or unpleasant pictures to neutral or to each other. We also observed that the relationship between LEAS and dACC activity was present in both sexes but stronger in women than men. These results reinforce the concept that greater trait awareness of one's own emotional experiences is associated with greater engagement of the dACC during emotional arousal, which we suggest may reflect greater attentional processing of emotional information.
