“…Emotional expressions were task irrelevant and therefore were only implicitly processed by participants. In line with the proposed predominant role of the right hemisphere in emotional processing (Borod et al, 1998), BD patients might have perceived emotional faces as more emotional than healthy controls. This might also explain the increased right hemisphere involvement in BD euthymia in this study.…”

“…The localization of visual-emotional integration to the right hemisphere is also supported by existing research. Patients with right-sided lesions demonstrate impairment in visual identification of emotional stimuli compared to those with left-sided lesions (Borod et al, 1998), and emotionally salient stimuli are processed more rapidly when presented to the left visual field or right hemisphere (Burton and Levy, 1989). Functional MRI studies have also implicated the right temporal cortex in emotional processing (Narumoto et al, 2001;Wager et al, 2003).…”

The mechanism by which the brain integrates visual and emotional information remains incompletely understood, and can be studied through focal lesions that selectively disrupt this process. To date, three reported cases of visual hypoemotionality, a vision-specific form of derealization, have resulted from lesions of the temporo-occipital junction. We present a fourth case of this rare phenomenon, and investigate the role of the inferior longitudinal fasciculus (ILF) in the underlying pathophysiology. A 50-year-old right-handed male was found to have a right medial temporal lobe tumor following new-onset seizures. Interstitial laser ablation of the lesion was complicated by a right temporo-parieto-occipital intraparenchymal hemorrhage. The patient subsequently experienced emotional estrangement from visual stimuli. A lesion overlap analysis was conducted to assess involvement of the ILF by this patient's lesion and those of the three previously described cases, and diffusion tensor imaging was acquired in our case to further investigate ILF disruption. All four lesions specifically overlapped with the expected trajectory of the right ILF, and diminished structural integrity of the right ILF was observed in our case. These findings implicate the ILF in visual hypoemotionality, suggesting that the ILF is critical for integrating visual information with its emotional content.

“…Although not the primary aim of the study, we conducted additional analyses to investigate the effects of hemisphere, given the importance of cerebral dominance in theories of emotion and attention [5,38,47]. Three regions showed hemispheric effects, but none of these involved responses to the aversive or neutral distracters.…”

Emotion?attention network interactions during a visual oddball task

Emotional and attentional functions are known to be distributed along ventral and dorsal networks in the brain, respectively. However, the interactions between these systems remain to be specified. The present study used event-related functional magnetic resonance imaging (fMRI) to investigate how attentional focus can modulate the neural activity elicited by scenes that vary in emotional content. In a visual oddball task, aversive and neutral scenes were presented intermittently among circles and squares. The squares were frequent standard events, whereas the other novel stimulus categories occurred rarely. One experimental group [N = 10] was instructed to count the circles, whereas another group [N = 12] counted the emotional scenes. A main effect of emotion was found in the amygdala (AMG) and ventral frontotemporal cortices. In these regions, activation was significantly greater for emotional than neutral stimuli but was invariant to attentional focus. A main effect of attentional focus was found in dorsal frontoparietal cortices, whose activity signaled task-relevant target events irrespective of emotional content. The only brain region that was sensitive to both emotion and attentional focus was the anterior cingulate gyrus (ACG). When circles were task-relevant, the ACG responded equally to circle targets and distracting emotional scenes. The ACG response to emotional scenes increased when they were task-relevant, and the response to circles concomitantly decreased. These findings support and extend prominent network theories of emotion -attention interactions that highlight the integrative role played by the anterior cingulate. D
