Multimodal Imaging Evidence for a Frontoparietal Modulation of Visual Cortex during the Selective Processing of Conditioned Threat

Abstract: Emotionally salient cues are detected more readily, remembered better, and evoke greater visual cortical responses, compared to neutral stimuli. The current study used concurrent EEG-fMRI recordings to identify large-scale network interactions involved in the amplification of visual cortical activity when viewing aversively conditioned cues. To generate a continuous neural signal from peri-calcarine visual cortex, we presented rhythmic (10/sec) phase-reversing gratings, the orientation of which predicted the p… Show more

“…Of note, similar to previous findings regarding emotion effects for pictures (Bisby, Horner, Hørlyck, & Burgess, 2016), despite similar activation levels in the amygdala, visual cortex responses markedly differed between negative and neutral stimuli. A consistent emotional response to aversive stimuli across different tasks in the visual cortex, but not the amygdala, has also been reported by Villalta-Gil et al (2017) and highlights the role of extra-amygdalar sources in emotional enhancement of visual processing (Pessoa & Adolphs, 2010;Petro et al, 2017), likely including the sensory cortices themselves (Miskovic & Anderson, 2018). For fearful faces, amygdala activation was elevated in both hemispheres, but there was a trend for a stronger emotion effect in the left amygdala.…”

“…The present study suggests that such competitive interac tions are most pronounced in situations in which threat cues are defined by multiple features, again paralleling canonical findings in selective attention and visual search (Treisman & Kanwisher, 1998). In line with this notion, recent evi dence from concurrent EEG-fMRI recordings during aver sive Pavlovian conditioning suggests that the same cortical regions associated with spatial and feature-based attention may also be involved in the selection of threat cue represen tations (Petro et al, 2017). Thus, multimodal neuroimaging with the present experimental design may allow refining and testing of the hypothesis that frontoparietal attention networks under the control of limbic circuits mediate the selective visuocortical facilitation of threat (Yin, Liu, Petro, Keil, & Ding, 2018).…”
