Introduction:
Emotions constitute an inherent aspect of human nature, profoundly shaping how we view the world. Among the various emotions we experience on a daily basis, anxiety holds particular significance for our survival (Bishop 2007; Fox and Shackman 2019; Grupe and Nitschke 2013; Hartley and Phelps 2010). The current study used functional magnetic resonance imaging (fMRI) to examine whether state anxiety modulated brain activity in response to emotionally-charged visual images.
Methods:
Our study recruited 53 participants, and participants were instructed to complete an emotional reactivity task in the MRI scanner. Within this task, participants underwent a block design paradigm consisting of three emotional conditions (i.e., positive, negative, or neutral). After scanning, participants completed the State-Trait Anxiety Inventory (STAI; Spielberger and Gonzalez-Reigosa 1971). We then used the intersubject representational similarity analysis (ISRSA) to analyze which brain regions might reveal significant associations between individual variations in state anxiety and neural representations of the three valence conditions.
Results:
Our results showed that the extrastriate cortex, in particular the fusiform gyrus and area MT, was the sole regions whose activity patterns across all three emotional conditions covaried with state anxiety (Figure 1). Importantly, we show that this brain-behavior association is revealed when treating state anxiety data as a multidimensional response pattern, rather than as a single composite score. Our findings suggest that ISRSA using multivariate distances may be more sensitive in identifying the shared geometries between self-report questionnaires and brain imaging data.
Conclusions:
Overall, these findings suggest a possible influence of state anxiety on extrastriate cortical activity, which in turn may shape how we perceive and interpret the world around us. Our data provide a useful starting point for future studies that might aim to experimentally induce anxious states and document the link between extrastriate cortical activity and the perception of emotional scenes.
