    ABSTRACT: This study examined neural processes of resilience during aversive interoceptive processing. Forty-six individuals were divided into three groups of resilience Low (LowRes), high (HighRes), and normal (NormRes), based on the Connor-Davidson Resilience Scale (2003). Participants then completed a task involving anticipation and experience of loaded breathing during functional magnetic resonance imaging (fMRI) recording. Compared to HighRes and NormRes groups, LowRes self-reported lower levels of interoceptive awareness and demonstrated higher insular and thalamic activation across anticipation and breathing load conditions. Thus, individuals with lower resilience show reduced attention to bodily signals but greater neural processing to aversive bodily perturbations. In low resilient individuals, this mismatch between attention to and processing of interoceptive afferents may result in poor adaptation in stressful situations.

    ABSTRACT: This study compared exercise-induced hypoalgesia (EIH) between African Americans (AAs, n=16) and non-Hispanic Whites (NHWs, n=16), and examined the potential influence of physical activity (PA) on the racial/ethnic difference in EIH. The PA levels were quantified using a questionnaire, and intensity of electrical stimulus to produce moderate pain was individually determined. Participants squeezed a hand dynamometer at 25% of their maximal strength for three minutes, followed by a three-minute post-exercise rest. Numeric ratings to electrical stimulus at the pre-determined intensity were recorded every one minute during and after exercise. Compared to NHWs, AAs reported less lifestyle PA. Both AAs and NHWs showed EIH, but AAs exhibited a smaller magnitude of EIH than NHWs. However, this difference in EIH disappeared after controlling for the lifestyle PA levels. The results suggest that AAs exhibit less efficient pain modulation than NHWs, and AAs' reduced PA could potentially explain the observed difference in EIH.

    ABSTRACT: Errors are unpredictable events that have the potential to cause harm. The error-related negativity (ERN) is the electrophysiological index of errors and has been posited to reflect sensitivity to threat. Intolerance of uncertainty (IU) is the tendency to perceive uncertain events as threatening. In the present study, 61 participants completed a self-report measure of IU and a flanker task designed to elicit the ERN. Results indicated that IU subscales were associated with the ERN in opposite directions. Cognitive distress in the face of uncertainty (Prospective IU) was associated with a larger ERN and slower reaction time. Inhibition in response to uncertainty (Inhibitory IU) was associated with a smaller ERN and faster reaction time. This study suggests that sensitivity to the uncertainty of errors contributes to the magnitude of the ERN. Furthermore, these findings highlight the importance of considering the heterogeneity of anxiety phenotypes in relation to measures of threat sensitivity.

    ABSTRACT: During the past 30 years, experimental psychopathologists have conducted many studies aiming to elucidate the cognitive abnormalities that may figure in the etiology and maintenance of OCD. In this paper, we review research on both dysfunctional beliefs and cognitive deficits in OCD, as findings from both traditional self-report and information-processing approaches provide distinct sources of information concerning cognitive abnormalities. First, we discuss dysfunctional beliefs and metacognitive beliefs implicated in the disorder. Research has identified a number of maladaptive appraisals (e.g., heightened responsibility) and metacognitive beliefs (e.g., need to control one's thoughts) that are associated with the disorder, yet these are not invariably present in all cases of OCD. Next, we review the literature on memory and attentional deficits and biases in OCD. This line of research shows inconsistent evidence for deficits in memorial and attentional processes, but does indicate that people with the disorder have memory and attention biases that may be related to metacognitive beliefs about their ability to remember and attend to stimuli. Finally, we discuss recent work that suggests that people with OCD have reduced access to internal states, thus causing them to engage in rituals to resolve persistent uncertainty. Implications and future directions are discussed.

    ABSTRACT: This Special Issue focuses on the auditory-evoked mismatch negativity (MMN), an electrophysiological index of change, and its reduction in schizophrenia. The following brief review is an attempt to complement the behavioral and clinical contributions to the Special Issue by providing basic information on synaptic interactions and processing in auditory cortex. A key observation in previous studies is that the MMN involves activation of cortical N -methyl-D-aspartate (NMDA) receptors. Yet, NMDA receptor activation is regulated by a number of synaptic events, which also may contribute to the MMN reduction in schizophrenia. Accordingly, this review will focus on synaptic interactions, notably inhibitory regulation of NMDA receptor-mediated activity, in auditory cortex.

    ABSTRACT: Anxious states can alter attention, impairing goal-directed processing in favor of bottom-up capture. However, it is still unclear whether anxiety-related biases already influence the earliest stage of information processing, especially for unattended threat-related stimuli. Here we tested, using EEG, if the amplitude of the first component of the Visual Evoked Potentials (C1) to simple visual stimuli (either neutral or threat-related) varied depending on anxiety level and task demands. Results showed that anxiety altered goal-directed processing, reducing P300 amplitude to target stimuli, while it increased the C1 to irrelevant stimuli, regardless of their emotional content. Moreover, enhanced load at fixation reduced the amplitude of this component to neutral stimuli, but this early filtering effect was abolished by state anxiety. These results shed light on the time-course of attentional biases in anxiety, confirming that this transient state can enhance bottom-up capture as early as in V1, at the expense of goal-directed processing.

    ABSTRACT: Evidence suggests that anomalous mismatch negativity (MMN) in schizophrenia is related to glutamatergic abnormalities, possibly involving N-methyl-D-aspartate (NMDA) receptors. Decreased cortical expressions of NMDA receptor subunits have been observed in schizophrenia, though not consistently. To aid with integration and interpretation of previous work, we performed a meta-analysis of effect sizes of mRNA or protein levels of the obligatory NR1 subunit in prefrontal cortex from people with schizophrenia. In schizophrenia compared to unaffected controls the pooled effect size was -0.64 (95% confidence interval: -1.08 to -0.20) for NR1 mRNA reduction and -0.44 (95% confidence interval: -0.80 to -0.07) for NR1 protein reduction. These results represent the first step to a deeper understanding of the region-specific, cell-specific, and stage-specific NMDA receptor hypofunction in schizophrenia, which could be linked to mismatch negativity deficits via transgenic and pharmacological animal models.

    ABSTRACT: The early detection of young people at-risk of developing a severe mental illness like schizophrenia offers the opportunity of introducing treatment earlier than currently possible. There is some evidence that early intervention improves prognosis and functional outcome, or even prevents the full clinical manifestation of the condition in some individuals. A key prerequisite to facilitate early intervention would be a biomarker that can reliably predict a transition to schizophrenia. A smaller event-related mismatch negativity (MMN) potential has emerged as one of the most robust psychophysiological finding in schizophrenia akin of a biomarker of the condition. More recent research further demonstrates that MMN, but also P3a amplitudes, are already reduced in the prodromal phase of illness. Several lines of pre-clinical and clinical research support this notion and are reviewed in this article together with current obstacles, which are still limiting the translation of MMN as a biomarker into clinical practice.

    ABSTRACT: The mismatch negativity (MMN) is thought to be an index of the automatic activation of a specialized network for active prediction and deviance detection in the auditory cortex. It is consistently reduced in schizophrenic patients and has received a lot of interest as a clinical and translational tool. The main neuronal hypothesis regarding the mechanisms leading to a reduced MMN in schizophrenic patients is a dysfunction of NMDA receptors (NMDA-R). However, this hypothesis has never been implemented in a neuronal model. In this paper, we examine the consequences of NMDA-R dysfunction in a neuronal model of MMN based on predictive coding principle. I also investigate how predictive processes may interact with synaptic adaptation in MMN generations and examine the consequences of this interaction for the use of MMN paradigms in schizophrenia research.

    ABSTRACT: The present study investigated the effect of emotion on response inhibition and error monitoring using event-related potentials. Participants performed an emotional stop-signal task that required response inhibition to briefly presented threatening and neutral visual stimuli. Negative, arousing pictures improved behavioral performance by decreasing the stop-signal reaction time and increasing the inhibitory rate, but had no enhancing effect on inhibitory processing at the electrophysiological level (N2-P3 complex). The perceptual processing of threatening stop-signals resulted in a larger and earlier N1 component. The Pe component, associated with conscious evaluation or affective processing of an error, was stronger in negative than in neutral trials. The stronger Pe correlated with superior task performance in the emotional condition. Prioritized perceptual processing of the stop-signal was associated with better conscious error monitoring. These results support the hypothesis that threatening, arousing stimuli improve behavioral inhibitory performance and error monitoring due to the enhancement of perceptual processing.

    ABSTRACT: The current study examines anxiety and age associations with attention allocation and physiological response to threats and rewards. Twenty-two healthy-adults, 20 anxious-adults, 26 healthy-youth, and 19 anxious-youth completed two eye-tracking tasks. In the Visual Scene Task (VST), participants' fixations were recorded while they viewed a central neutral image flanked by two threatening or two rewarding stimuli. In the Negative Words Task (NWT), physiological response was measured by means of pupil diameter change while negative and neutral words were presented. For both tasks, no interaction was found between anxiety and age-group. In the VST, anxious participants avoided the threatening images when groups were collapsed across age. Similarly, adults but not adolescents avoided the threatening images when collapsed across anxiety. No differences were found for rewarding images. In NWT, all subjects demonstrated increase in pupil dilation after word presentation. Only main effect of age emerged with stronger pupil dilation in adults than children. Finally, maximum pupil change was correlated with threat avoidance bias in the scene task. Gaze patterns and pupil dilation show that anxiety and age are associated with attention allocation to threats. The relations between attention and autonomic arousal point to a complex interaction between bottom-up and top-down processes as they relate to attention allocation.

    ABSTRACT: Increased resilience is associated with better health outcomes and reduced morbidity in response to injury and homeostatic perturbations. Proper functioning of the salience network (SN) and modulation of the default mode network (DMN) by SN may play a role in adaptively responding to stress. Here, we demonstrate that resilient personality in healthy subjects is associated with SN and DMN connectivity patterns and that these patterns are influenced by sex. While connectivity of SN with several brain regions including right anterior insula was significantly associated with resilient personality in both men and women, results suggest that increased functional integration of anterior DMN preferentially benefits women while increased functional integration of posterior DMN preferentially benefits men in terms of resilience. These findings may relate to previous demonstrations that men and women engage different information processing and behavioral strategies to achieve resilience and highlight the importance of considering sex in resilience research.
