“…Previous research has shown that SBS contexts typically engender a variety of behavioral and physiological SBS responses including sustained vACC activation, unique neural network configurations, and enhanced connectivity between regions integral for emotion (dACC, vACC, and mPFC) and saliency networks (IPL, insula, and STS). This evidence collectively suggests increased emotional processing and heightened awareness of negatively arousing or stressful information (Forbes et al, 2018;Liu et al, 2020Liu et al, , 2021Amey et al, 2022). We sought to understand if threatened women can transmit their stress to otherwise non-threatened partners, does it hurt or benefit the woman directly under threat, and to what extent can this come at a cost to their otherwise non-threatened partners?…”

IntroductionThis study delves into the intricacies of emotional contagion and its impact on performance within dyadic interactions. Specifically, it focuses on the context of stereotype-based stress (SBS) during collaborative problem-solving tasks among female pairs. Through an exploration of emotional contagion, this study seeks to unveil its underlying mechanisms and effects.MethodsLeveraging EEG-based hyperscanning technology, we introduced an innovative approach known as the functional graph contrastive learning (fGCL), which extracts subject-invariant representations of neural activity patterns from feedback trials. These representations are further subjected to analysis using the dynamic graph classification (DGC) model, aimed at dissecting the process of emotional contagion along three independent temporal stages.ResultsThe results underscore the substantial role of emotional contagion in shaping the trajectories of participants' performance during collaborative tasks in the presence of SBS conditions.DiscussionOverall, our research contributes invaluable insights into the neural underpinnings of emotional contagion, thereby enriching our comprehension of the complexities underlying social interactions and emotional dynamics.

During performance in everyday contexts, multiple networks draw from shared executive resources to maintain attention, regulate arousal, and problem solve. At times, requirements for attention and self-regulation appear to be in competition for a "limited pool" of resources. How does the brain attempt to resolve conflicts arising from multiple processing demands? In the present study, participants were exposed to either a stress or control prime, after which electroencephalographic (EEG) activity was recorded as they solved math problems. Phase-locking was examined within four networks implicated in math-solving and evaluative stress: frontopareital (FP), default mode (DM), emotion generation (EG), and emotion regulation (ER) networks. Findings revealed differing strategies, depending on the presence of stress: states dominated by frontopareital and emotion regulation network dynamics supported optimum performance generally, while during stress, states dominated by emotion regulation and default mode networks are more important for performance. Implications for networks' cooperative dynamics and DMN's role in coping are considered.

Neurocognitive impairment is present in cirrhosis and may be more severe in cirrhosis with the overt hepatic encephalopathy (OHE). Liver transplantation (LT) may reverse the impaired brain function. MRI of resting-state functional connectivity can help unravel the underlying mechanisms that lead to these cognitive deficits and recovery. Sixty-four cirrhotic patients (28 with OHE; 36 without) and 32 healthy controls were recruited for resting-state fMRI. The patients were scanned before and after LT. We evaluated pre- and postsurgical neurocognitive performance in cirrhotic patients using psychomotor tests, i.e. number connection test (NCT) and digit symbol test (DST). Network-based statistics found significant disrupted connectivity in both groups of cirrhosis with OHE and without compared to controls. However, the presurgical connectivity disruption in patients with OHE was included in a greater number of connections than those without (65 vs. 17). The decrease in FC for both OHE and non-OHE patient groups was reversed to the level of controls after LT. An additional hyperconnected network (i.e., higher than controls) was observed in OHE patients after LT (p=0.009). Regarding the neural-behavior relationship, the functional network that predicted cognitive performance in healthy individuals, showed no correlation in presurgical cirrhotic patients. Such an impaired neural-behavior relationship was re-established after LT for non-OHE patients but not for OHE. OHE patients displayed abnormal hyperconnectivity and persistently impaired neural-behavior relationship after LT. Our results suggest that patients with OHE may undergo a different trajectory of postsurgical neurofunctional recovery in comparison to those without, which needs further clarification in the future study.
