In conclusion, our study provides evidence of a neuroanatomical and functional distinction between state and trait anxiety. We found several differences in the structural–functional patterns across anxiety types: (1) trait anxiety was associated to both structural covariance of Default Mode Network (DMN), with an increase in dorsal nodes and a decrease in its ventral part, and to rs-FC of DMN within frontal regions (2) state anxiety, instead, was widely related to rs-FC of Salience Network and of DMN, specifically in its ventral nodes, but not associated with any structural pattern. To study this, we assessed 42 healthy participants with the State-Trait Anxiety Inventory and then investigated with MRI to characterize structural grey matter covariance and resting-state functional connectivity (rs-FC). It is yet unclear whether brain structural and functional features may distinguish these aspects of anxiety. Researchers differentiate aspects of anxiety into state and trait, respectively defined as a more transient reaction to an adverse situation, and as a more stable personality attribute in experiencing events. Moreover, the higher the LSAS-J score was, the greater the increase was in HR deceleration (correlation coefficient rs = 0.Anxiety is a mental state characterized by an intense sense of tension, worry or apprehension, relative to something adverse that might happen in the future. Our results showed that HR deceleration was greater for the HSA compared with the LSA group. Participants were assigned to a high social anxiety (HSA) or low social anxiety (LSA) group on the basis of cut-off scores indicative of clinical levels of stress as per the Japanese version of the Liebowitz Social Anxiety Scale (LSAS-J). We used the maximum HR deceleration between 0 s and 3 s after stimulus onset as an indicator of emotional stress. We conducted a gaze detection experiment to examine the effects of social anxiety on autonomic response, namely heart rate (HR) response. The gaze of others is known to frequently induce social anxiety.
